PAM-XIAMEN can offer 6H SiC wafer with n type or semi-insulating. Silicon carbide wafer is a material presenting different crystalline structures called polytypes, which has more than 250 structures. Different polytypes has different atomic stacking sequences. Polytypes generate the cubic, hexagonal or rhombohedral structures, which include [...]

The vibrational energy of the molecule is larger than the rotational energy. When the vibrational energy level transition occurs, it is inevitably accompanied by the transition of the rotational energy level, so the pure vibrational spectrum cannot be measured, but only the vibrational-rotational spectrum [...]

With the sudden outbreak of COVID-19, some vertical categories that are not usually paid attention to quickly became popular. Materials related to epidemic prevention and control, such as masks, goggles, and disinfectant, have become popular. Among them, UVC (Ultra Violet C radiation) LED with [...]

Carrier mobility is often used to refer to the overall movement of electrons and holes in semiconductors. Mobility refers to the average drift velocity of carriers (electrons and holes) under the action of a unit electric field. That is a measure of the speed [...]

The Silicon crystal orientations that we often hear are <100>, <110> and <111>(shown as Fig. 1), respectively indicating a crystallographic family. The single crystal silicon structure belongs to cubic crystals, and the <100> crystal orientation family represents six crystal orientations: [100], [010], [001], [100], [0-10], and [...]
