摘 要: 采用计算机控制的快速辐射加热、超低压CVD(RRH/VLP-CVD)方法生长了Si/Si0.7Ge0.3/Sip-型调制掺杂双异质结构.研究了该结构的输运性质,其空穴霍尔迁移率高达300cm2/V·s(300K,薄层载流于浓度ps为2.6×1013cm-2)和8400cm2/V·s(77K,ps为1.1×1013cm-2). Abstract St/Si0.7Ge0.3/Si p-type Modulation Doped Double Heterostructures have been grown by RRH/VLP-CVD (Rapid Radiant Heating/Very Low Pressure-CVD). The transport property is investigated. Hole Hall mobilities as high as 300cm2/V·s (300K) and 8400cm2/V·s(77K) have been obtained. These are the highest values reported so far.
