Silicon Carbide (SiC) is a wide bandgap material. Wide bandgap technologies have many advantages compared to Silicon. Operating temperatures are higher, heat dissipation is improved and switching and conduction losses are lower. However, wide bandgap materials are more difficult to mass produce compared to silicon based ones.
we focus on STM images with atomic resolution. Such images are routinely achieved at 45K with sample bias as FIG. 1: (color online) (a) 109 eV LEED pattern of the 6H-SiC(0001) 6R3 reconstruction. (b) 40 × 40 nm2 STM image
