Wafer-scale Semiconductor Grafting: Enabling High-Performance, Lattice-Mismatched Heterojunctions
Jie Zhou, Qiming Zhang, Jiarui Gong +14
Semiconductor heterojunctions are foundational to many advanced electronic and optoelectronic devices. However, achieving high-quality, lattice-mismatched interfaces remains challe…
Si/AlN p-n heterojunction interfaced with ultrathin SiO2
Haris Naeem Abbasi, Jie Zhou, Ding Wang +9
Ultra-wide bandgap (UWBG) materials hold immense potential for high-power RF electronics and deep ultraviolet photonics. Among these, AlGaN emerges as a promising candidate, offeri…
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…
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…
