Abstract

We have investigated a lateral conduction midinfrared photodetectors by using photoionization of holes in the self-assembled Ge/Si quantum dots. A broad mid-infrared photocurrent spectrum was observed in photon energy range of 120-400 meV due to intersubband transition in the valence band of self-assembled Ge quantum dots. The peak responsivity was 134 mA/W at photon energy range of 240 meV at T=10 K.
