Single-crystalline GaAs/Si Heterojunction Tunnel Diodes Interfaced by an Ultrathin Oxygen-enriched Layer
Jie Zhou, Yifan Wang, Ziqian Yao +13
We report the fabrication and characteristics of GaAs/Si p+/n+ heterojunction tunnel diodes. These diodes were fabricated via grafting the freestanding single-crystalline p-type de…
Grafted AlGaAs/GeSn Optical Pumping Laser Operating up to 130 K
Jie Zhou, Daniel Vincent, Sudip Acharya +16
Group IV GeSn double-heterostructure (DHS) lasers offer unique advantages of a direct bandgap and CMOS compatibility. However, further improvements in laser performance have been b…
Characterization of AlGaAs/GeSn heterojunction band alignment via X-ray photoelectron spectroscopy
Yang Liu, Jiarui Gong, Sudip Acharya +12
GeSn-based SWIR lasers featuring imaging, sensing, and communications has gained dynamic development recently. However, the existing SiGeSn/GeSn double heterostructure lacks adequa…
Influences of ALD AlO on the surface band-bending of c-plane, Ga-face GaN and the implication to GaN-collector npn heterojunction bipolar transistors
Jiarui Gong, Jisoo Kim, TienKhee Ng +7
Due to the lack of effective p-type doping in GaN and the adverse effects of surface band-bending of GaN on electron transport, developing practical GaN heterojunction bipolar tran…
Lattice-mismatched semiconductor heterostructures
Dong Liu, Sang June Cho, Jung-Hun Seo +19
Semiconductor heterostructure is a critical building block for modern semiconductor devices. However, forming semiconductor heterostructures of lattice-mismatch has been a great ch…
