Abstract

Cathodoluminescence (CL) and optical transmission spectroscopy were used to study the optical properties of molecular-beam-epitaxy (MBE) grown GaN with different doping levels. The 1-μm-thick samples were grown by plasma-induced MBE on c-plane Al ₂O ₃ substrate. The absorption measurements were performed at 2 K with a 250 W tungsten-halogen lamp. The CL measurements showed that Mn-doping concentrations around 10 ²⁰ cm ^-3 reduced the near band edge emission intensity by around one order of magnitude.
