Values of ft range from 30 GHz for power devices to 200 GHz for the highest speed structures. Interestingly, the improvements being made to silicon BJTs such as epitaxial bases, polysilicon emitters, and silicided bases, make use of deposited active layers, which is reminiscent of III-V technologies based on epitaxy.

Step formation on hydrogen-etched 6H-SiC{0 0 0 1} …

The formation of step bunches and/or facets on hydrogen-etched 6H-SiC(0 0 0 1) and (0 0 0 1 ¯) surfaces has been studied, using both nominally on-axis and intentionally miscut (i.e. vicinal) substrates. It is found that small miscuts on the (0 0 0 1) surface produce full unit-cell high steps, while half unit-cell high steps are observed on the (0 0 0 1 ¯) surface.
