Abstract
Description
図1は、本発明の実施の形態1に係る化合物半導体デバイスを示す断面図である。SiC基板1上にGaNバッファ層2が形成されている。GaNバッファ層2上にAlGaNチャネル層3が形成されている。AlGaNチャネル層3上にゲート電極4、ソース電極5及びドレイン電極6が形成されている。
図5は、本発明の実施の形態2に係る化合物半導体デバイスの回路図である。本実施の形態では、実施の形態1の構成に加えて、ソース電極5とドレイン電極6との間に強相関電子系材料15が接続されている。これにより、電荷が抜けるパスが増えるので効果が増す。なお、ソース側の強相関電子系材料12を省略してドレイン側の強相関電子系材料15のみ設けてもよく、実施の形態1と同様の効果を得ることができる。
