Title: Resonance tunnel diode
Inventor: ANDO YUJI
IPC: H01L29/88
Filed: 1987-03-26
Abstract: PURPOSE:To realize the excellent controllability of a negative resistance threshold voltage and an excellent peak/valley ratio by utilizing the difference between the electron affinities of N-type layers on both ends and the electron affinity of a quantum well layer. CONSTITUTION:On both sides of a 1st semiconductor layer 11 in which a resonance level of electrons is formed, nondoped 2nd semiconductor layers 12 and 12' which have smaller electron affinities than the 1st semiconductor layer 11 and thicknesses thin enough for electrons to be transmitted by a tunnel effect are formed. On the sides of the 2nd semiconductor layers 12 and 12' opposite to the the 1st semiconductor layer, 3rd semiconductor layers 13 and 13' including at least one type layer which have larger electron affinities than the 1st semiconductor layer 11 are formed. Electrodes 10 and 10' which have ohmic contacts with the N-type layers of the 3rd semiconductor layers 13 and 13 ' are formed. With this constitution, a resonance tunnel diode whose threshold voltage shows a negative resistance and can be varied with the excellent controllability and which shows a high peak current in the current-voltage characteristics and has an excellent peak/valley ratio can be realized.
