Parameters of thulium

A study was made of GaN crystals grown by HVPE and MOCVD. Thulium was introduced by diffusion. It is shown that the Tm rare-earth ion acts as an acceptor in a GaN semiconductor matrix if the undoped crystal contains deep-level defects. Intracenter f-f transitions characteristic of Tm were observed in the short-and long-wavelength spectral regions. The short-wavelength emission intensity is Get price

Gallium Nitride (GaN) Technology

Gallium Nitride (GaN) is a direct band gap semiconductor, with a wide band gap of 3.4 eV (electronvolt), 2.4x wider than Gallium Arsenide (GaAs) and 3x wider than Silicon. This makes GaN better suited for high-power and high-frequency devices, as it derives lower switching and conduction losses. In turn, this translates to lower size, weight Get price
