[Q]: Information: - DLG (Dark Latin Groove) is a salsa band that mixes salsa, reggae, reggaeton, and hip-hop. The group was brought together in New York by producer Sergio George (who also signed them to his record company Sir George Records) and included Huey Dunbar, Fragancia, and James "Da Barba" de Jesus. - Gotcha ! is DLG 's third album . It includes well known singles such as Volvere . It is the last album to feature Huey Dunbar as the lead singer . It received a Grammy nomination for Best Salsa Album . - Huey Dunbar (born Eustace Dunbar IV; May 15, 1974) is the former singer of Dark Latin Groove. Born to a Puerto Rican mother and a Jamaican father, he was exposed to music since his earliest years due to his parents' musical careers. His hits with the band included "La quiero a morir", "Juliana", "No Morira", "Volvere", "Todo mi corazon", and a remake of Ricardo Montaner's original classic "Me va a extranar". In 2000, he split up with DLG and since had a solo career which, though commercially successful, has not equaled the diverse acclaim accorded DLG. For his first solo album he was awarded "Best New Artist" by Billboard magazine, and received a Grammy nomination. The album was certified Gold and Platinum by RIAA. In 2007 Dunbar was invited by producer Sergio George to reunite with DLG, but Dunbar refused. The seven-year gap between Dunbar's 2003 and 2010 albums has not been publicly explained, but is uncharacteristic of a popular star at the peak of his career. Sales of "Huey Dunbar IV" have been strong in Latin America. In Billboard's Tropical Songs chart, the single "Te amare" had moved from the number 9 song to number 4. "Huey Dunbar IV", debuted on the Tropical Albums chart at Number 2 on March 20, 2010. Given the information, choose the subject and object entities that have the relation of 'performer'.

[Q]: Information: - 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. - Jean - Claude Simon ( born 1948 ) is a researcher in the field of semiconductor optical amplifiers . Since 1998 he was permanent professor at ENSSAT / University of Rennes1 . Director of FOTON , research department in Optics and Optoelectronics for Telecom , affiliated to CNRS . - An extrinsic semiconductor is one that has been "doped", that is, into which a doping agent has been introduced, giving it different electrical properties than the intrinsic (pure) semiconductor. This doping involves adding dopant atoms to an intrinsic semiconductor, which changes the electron and hole carrier concentrations of the semiconductor at thermal equilibrium, the temperature at which two adjacent substances exchange no heat energy. Dominant carrier concentrations in an extrinsic semiconductor classify it as either an n-type or p-type semiconductor. The electrical properties of extrinsic semiconductors make them essential components of many electronic devices. - In physics, chemistry, and electronic engineering, an electron hole (often simply called a hole) is the lack of an electron at a position where one could exist in an atom or atomic lattice. Since in a normal atom or crystal lattice the negative charge of the electrons is balanced by the positive charge of the atomic nuclei, the absence of an electron leaves a net positive charge at the hole's location. Holes in a semiconductor crystal lattice can move through the lattice as electrons can, and act similarly to positively-charged particles. They play an important role in the operation of semiconductor devices such as transistors, diodes and integrated circuits. However they are not actually particles, but rather quasiparticles; they are different from the positron, which is the antiparticle of the electron. (See also Dirac Sea.) - In physics, a charge carrier is a particle free to move, carrying an electric charge, especially the particles that carry electric charges in electrical conductors. Examples are electrons, ions and holes. In a conducting medium, an electric field can exert force on these free particles, causing a net motion of the particles through the medium; this is what constitutes an electric current. In different conducting media, different particles serve to carry charge: - Modern Electronics was a hobbyist magazine published from October 1984 to March 1991. It became "Computer Craft" in April 1991 and the name changed again to "MicroComputer Journal" in January 1994. Modern Electronics, Inc. was owned by CQ Communications, Inc, the publishers of "CQ Amateur Radio". - 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. - In condensed matter physics and materials science, an amorphous (from the Greek "a", without, "morphe", shape, form) or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal. In some older books, the term has been used synonymously with glass. Nowadays, "Glassy solid" or "Amorphous solid" is considered to be the overarching concept, and glass the more special case: A glass is an amorphous solid that exhibits a glass transition. Polymers are often amorphous. Other types of amorphous solids include gels, thin films, and nanostructured materials such as glass.
