摘要：

The　effect　of　different　base　structural　parameters　on　SiGe　Heterojunction　Phototransistor　(HPT)　performance　is　analyzed　in　this　paper.　It　proposes　a　reference　for　designing　SiGe　HPT　with　both　high　responsivity　and　high　characteristic　frequency.　Responsivity　of　5.58　A/W　and　characteristic　frequency　of　21.29　GHz　for　850　nm　light　are　achieved　when　the　thickness　of　base　layer　is　70nm　with　the　doping　concentration　of　1.0×1019　cm-3.　©　2018　IEEE.
