The high power properties of heterojunction FETs (H-FET) have been investigated. The H-FETs are fabricated by using a strained AlGaAs/GaInAs/GaAs/AlGaAs selectively-doped double heterojunction structure. As compared with GaAs MESFETs, the H-FETs show

Photopumped blue laser oscillation was achieved up to near room temperature (280 K) in a ZnS0.18Se0.82/ZnSe multilayer structure grown by MOVPE. This significant improvement in the lasing temperature is attributed to the higher heterobarrier which pr
