Semiconductor heterostructures based on AlAs/GaAs and other III-V compounds have been the focus of active research for some time now. Ih the last decade, a new heterostructure material, the strained Si/SiGe system, has emerged. This heterojunction technology can potentially be integrated into the current VLSI environment with large-scale impact in the growing microelectronics market. Si/SiGe heterojunction bipolar transistors with cut-off frequencies exceeding 100 GHz and other electronic and optical devices with superior properties compared to all-Si technology have been demonstrated in laboratories worldwide.
