Expedited Award for Novel Research: Electromodulation In- vestigation of Semiconductor Superlattices, Quantum Well and Heterojunctions

计划利用光反射和电反射的电调制技术研究和表征各种半导体结构，如超晶格、量子阱和异质结。蒙茅斯堡ETDL设施具有出色的MBE生长能力，他们已经在制备这种结构，特别是GaA1As/GaAs体系和GaAs掺杂超晶格（hipi结构）。虽然蒙茅斯大学有一定的技术，如光致发光、拉曼散射、透射电镜等来研究这些半导体系统，但他们没有电调制光谱能力。因此，这将是一次资源、专业知识和兴趣的极好和非常及时的匹配。

The PI intends to study and characterize various semiconductor structures such as superlattices, quantum wells and heterojunctions by the electromodulation techniques of photoreflectance and electroreflectance. The Ft. Monmouth ETDL facility has an excellent MBE growth capability and they are already preparing such structures particularly the GaA1As/GaAs system and GaAs doping superlattices (hipi structures). Although Ft. Monmouth has certain techniques such as photoluminescence, Raman scattering, TEM, etc. to study these semiconductor systems they do not have an electromodulation spectroscopy cability. Therefore, this would be an excellent and very timely match-up of resources, expertise and interests.
