Fundamentals of Gallium Nitride Power Transistors
epc-co.comEPC’s enhancement mode gallium nitride (eGaN®) transistors behave very similarly to silicon power MOSFETs. A positive bias on the gate relative to the source causes a field effect which attracts electrons that complete a bidirectional channel between the drain and the source. A key difference between gallium nitride (GaN) and silicon is that

The mercury vapor lamp has an output in the short-wave UV range, between 220 and 320 nanometers (nm), and a spike of energy in the long-wave range, at 365 nm. This lamp is a good choice for clear coatings and thin ink layers and produces hard-surface cures and high-gloss finishes.
