Correlation of the MBE growth temperature, material quality, and performance of quantum cascade lasers
The influence of substrate temperature during the growth of quantum-cascade lasers using gas-source molecular-beam epitaxy on performance and crystal quality of quantum-cascade laser is investigated. Lower substrate temperature is consistently resulting in narrower X-ray diffraction satellites, and lower laser threshold current. This correlation is attributed to increased interface roughness at higher growth temperature. (c) 2012 Elsevier B.V. All rights reserved.
