Please answer the following question: Information: - An inductor, also called a coil or reactor, is a passive two-terminal electrical component that stores electrical energy in a magnetic field when electric current is flowing through it. An inductor typically consists of an electric conductor, such as a wire, that is wound into a coil. - Microelectronics is a subfield of electronics. As the name suggests, microelectronics relates to the study and manufacture (or microfabrication) of very small electronic designs and components. Usually, but not always, this means micrometre-scale or smaller. These devices are typically made from semiconductor materials. Many components of normal electronic design are available in a microelectronic equivalent. These include transistors, capacitors, inductors, resistors, diodes and (naturally) insulators and conductors can all be found in microelectronic devices. Unique wiring techniques such as wire bonding are also often used in microelectronics because of the unusually small size of the components, leads and pads. This technique requires specialized equipment and is expensive. - Pinyin, or Hany Pnyn, is the official romanization system for Standard Chinese in mainland China, Malaysia, Singapore, and Taiwan. It is often used to teach Standard Chinese, which is normally written using Chinese characters. The system includes four diacritics denoting tones. Pinyin without tone marks is used to spell Chinese names and words in languages written with the Latin alphabet, and also in certain computer input methods to enter Chinese characters. - Microfabrication is the process of fabricating miniature structures of micrometre scales and smaller. Historically, the earliest microfabrication processes were used for integrated circuit fabrication, also known as "semiconductor manufacturing" or "semiconductor device fabrication". In the last two decades microelectromechanical systems (MEMS), microsystems (European usage), micromachines (Japanese terminology) and their subfields, microfluidics/lab-on-a-chip, optical MEMS (also called MOEMS), RF MEMS, PowerMEMS, BioMEMS and their extension into nanoscale (for example NEMS, for nano electro mechanical systems) have re-used, adapted or extended microfabrication methods. Flat-panel displays and solar cells are also using similar techniques. - The C9 League is an alliance of nine elite universities in mainland China, analogous to the AAU in the United States, the U15 in Canada, the Russell Group in the UK, and the Go8 in Australia. The members of the C9 League are Fudan University, Harbin Institute of Technology, Nanjing University, Peking University, Shanghai Jiao Tong University, Tsinghua University, University of Science and Technology of China, Xi'an Jiaotong University, and Zhejiang University. Together they account for 3% of the country's researchers but receive 10% of national research expenditures. They produce 20% of the academic publications and 30% of total citations. - Wire bonding is the method of making interconnections(ATJ) between an integrated circuit (IC) or other semiconductor device and its packaging during semiconductor device fabrication. Although less common, wire bonding can be used to connect an IC to other electronics or to connect from one printed circuit board (PCB) to another. Wire bonding is generally considered the most cost-effective and flexible interconnect technology, and is used to assemble the vast majority of semiconductor packages. If properly designed, wire bonding can be used at frequencies above 100GHz. - Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high electrical resistance higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities ("doping") into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics. - Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit. - Peking University (abbreviated PKU and colloquially known in Chinese as Bida ; Chinese: , pinyin: Bijng Daxue), is a major Chinese research university located in Beijing and a member of the C9 League. It is the first modern national university established in China, founded as the Imperial University of Peking in 1898 as a replacement of the ancient Taixue or Guozijian, or Imperial Academy. It also served as the highest administration for education (ministry of education) in China at the beginning of its founding. By 1920, it had become a center for progressive thought. Peking University is consistently ranked as the top higher learning institution in mainland China. In addition to academics, Peking University is especially renowned for its campus grounds, and the beauty of its traditional Chinese architecture. - Tsinghua University (abbreviated THU; Chinese: , pinyin: Qnghua Daxue) is a research university located in Beijing, China, established in 1911. With strong research and training, Tsinghua University is consistently ranked as one of the top academic institutions in China, alongside Peking University. It is one of the nine members in the C9 League of universities. - Li Zhijian ( 1928 -- 2011 ) , was a pioneer of Chinese microelectronics . He was former Chief Director of the Institute of Microelectronics , Tsinghua University ; and the ex-Chairman of the Academic Committee , School of Information Science and Technology , Tsinghua University . - In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a pn junction connected to two electrical terminals. A vacuum tube diode has two electrodes, a plate (anode) and a heated cathode. Semiconductor diodes were the first semiconductor electronic devices. The discovery of crystals' rectifying abilities was made by German physicist Ferdinand Braun in 1874. The first semiconductor diodes, called cat's whisker diodes, developed around 1906, were made of mineral crystals such as galena. Today, most diodes are made of silicon, but other semiconductors such as selenium or germanium are sometimes used. - A research university is a university that expects all its tenured and tenure-track faculty to continuously engage in research, as opposed to merely requiring it as a condition of an initial appointment or tenure. Such universities can be recognized by their strong focus on innovative research and the prestige of their brand names. On the one hand, research universities strive to recruit faculty who are the most brilliant minds in their disciplines in the world, and their students enjoy the opportunity to learn from such experts. On the other hand, new students are often disappointed to realize their undergraduate courses at research universities are overly academic and fail to provide vocational training with immediate "real world" applications; but many employers value degrees from research universities because they know that such coursework develops fundamental skills like critical thinking.
