Latest Patents

Francoise Rambier holds a patent for a microwave transistor with a double heterojunction. This invention involves a microwave transistor made with group III-V materials, such as GaAs and AlGaAs. The transistor comprises a double heterojunction formed by a first layer of material with a large forbidden gap, n-doped, a second non-doped layer with a narrow forbidden gap, and a third p-doped layer with a wide forbidden gap. Under the influence of an electrical field, a two-dimensional electron gas may form at the interface with the first layer, while a two-dimensional hole gas may form at the interface with the third layer. By adjusting the thickness of the layers, the characteristics of the n and p channels can be made symmetrical.
