Doping in cubic silicon–carbide: Applied Physics Letters
We studied the energetics and the properties of impurity states that result from doping cubic silicon–carbide (3C–SiC) with aluminum (Al), boron (B), and nitrogen (N) atoms using the tight-binding linear coination of muffin-tin orbital atomic sphere approximation method. For Al doping, it is only favorable to substitute Al for Si atoms. The corresponding hole states contribute to a

The n-type blocking layer is 6 !J.m thick. The p-type base layer is 2 !J.m thick, and the p-type anode layer is 1.5 !J.m thick. The blocking layer is lightly doped with nitrogen, Nd = 4-5x1015 cm·3. Both p-type base layer and anode layer are doped with AI. Calculations based on blocking layer thickness and doping predict punch-through at 100V
Carbide Types in Knife Steels - Knife Steel Nerds
Jul 15, 2019· When sufficient tungsten is added to a 4%+ Cr steel, WC doesn’t form in larger amounts, but a different carbide type forms instead, W 6 C. The W 6 C carbide is much softer than WC as shown in the hardness chart. This carbide is seen even with T1 high speed steel which has 18% tungsten.
