Filed: 1994-04-05
Abstract: PURPOSE:To easily manufacture a quantum element such as a Mott-Stark-effect transistor or the like. CONSTITUTION:A GaAs/AlAs superlattice which has been laminated on a substrate is cut in a direction perpendicular to the surface of the substrate, and GaAs layers 3 which are exposed on cut faces are etched and removed selectively. Then, GaAs layers 4 are epitaxially grown to be triangular prism-shaped on cut faces of AlAs layers 2. An AlAs layer 5 is epitaxially grown so as to cover the GaAs layers 4. Then, a wire-shaped electrode 8 for application of an external electric field is formed on the AlAs layer 5. After that, the AlAs layer 5, the GaAs layers 4 and the AlAs layers 2 are etched so as to be patterned sequentially by making use of the electrode 8 as a mask. A one- dimensional quantum dot array in which quantum dots QDs having a structure in which the GaAs layers 4 are surrounded by the AlAs layers 2, 5 is formed, and it is used as a channel region.

Title: Radio telephone set calling system
Inventor: UCHIDA KOUHEI
IPC: H04W99/00
Filed: 1979-07-17
Abstract: PURPOSE:To make a connection possible even when information received by an automatic switchboard differs from that by a radio telephone set, by transferring switching information of a carrier to the radio telephone set in case that the radio telephone set makes no answer for a certain time.
