Progress of semiconductor superlattice phonon laser
摘要
Abstract
The coherent phonons at terahertz frequency have important applications in the field of detection and control of nanometer scale devices.Semiconductor superlattice phonon laser is an important way to realize the stable source of terahertz coherent phonon.Firstly, some methods about acoustic amplification in GHz-THz frequency range are reviewed.Next, the phonon amplification in superlattices, the working principles and design methods of superlattice acoustic Bragg reflectors and threshold of phonon laser are all elaborated.Then the research status on electrically pumped and optically pumped phonon lasers are summarized.Lastly, the applications for sub-terahertz phonon laser in the acoustic-electrons field are briefly discussed.The semiconductor superlattice phonon laser producing strong coherent phonons at terahertz frequency will have a much broader development prospect in multiple aspects, such as the detection and imaging of nanoscale devices.关键词
