Title: Resonance tunnel equipment
Inventor: TSUKADA KOJI
IPC: H01L29/66
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a resonance tunnel equipment operating at a high speed at the ambient temperature and having a large peak current/valley current. SOLUTION: The resonance tunnel equipment comprises a buffer layer, a quantum well layer 50 and barrier layers 41 formed on a GaAs substrate. A metamorphic buffer layer 20 is constituted of a plurality of InxGa1-xAs layers. In this case, the composition ratio x of the In is, for example, stepwisely changed from 0.1 to 0.5. The layers 41, 42 are each formed of an InAlAs, and the layer 50 is formed of an InGaAs. Since the metamorphic buffer layer is used, the crystallinity of the quantum well structure formed on the buffer layer is upgraded. Since the composition ratio of the In can be increased, potential barriers of the well layer and the barrier layer can be increased. Therefore, the ambient temperature operation can be performed, a crystal is continuously grown on the As substrate to increase the peak current/valley current, and the crystallinity as a while can be held.
