Journal ArticleDOI
Optical thermometry through infrared excited green upconversion emissions in Er3+–Yb3+ codoped Al2O3
TL;DR: In this article, the fluorescence intensity ratio (FIR) variation of green upconversion emissions at 523 and 545nm in the Er3+−Yb3+ codoped Al2O3 has been studied as a function of temperature using a 978nm semiconductor laser diode as an excitation source.
Journal ArticleDOI
Transfer print techniques for heterogeneous integration of photonic components
TL;DR: In this paper, the authors review some of the recent developments in layer transfer and particularly the use of the transfer print technology for enabling active photonic devices on rigid and flexible foreign substrates.
Journal ArticleDOI
Sharpened VO2 Phase Transition via Controlled Release of Epitaxial Strain
Daesu Lee,Jaeseong Lee,Kyung Song,Fei Xue,Si-Young Choi,Yanjun Ma,J. P. Podkaminer,Dong Liu,Shih-Chia Liu,Bongwook Chung,Wenjuan Fan,Sang June Cho,Weidong Zhou,Jaichan Lee,Long Qing Chen,Sang Ho Oh,Sang Ho Oh,Zhenqiang Ma,Chang-Beom Eom +18 more
TL;DR: This study develops an approach to control the MIT dynamics in epitaxial VO2 films by employing an intermediate template layer with large lattice mismatch to relieve the interfacial lattice constraints, contrary to conventional thin film epitaxy that favors lattice match between the substrate and the growing film.
Journal ArticleDOI
Single-crystalline germanium nanomembrane photodetectors on foreign nanocavities.
Zhenyang Xia,Haomin Song,Munho Kim,Ming Zhou,Tzu-Hsuan Chang,Dong Liu,Xin Yin,Kanglin Xiong,Hongyi Mi,Xudong Wang,Fengnian Xia,Zongfu Yu,Zhenqiang Jack Ma,Qiaoqiang Gan +13 more
TL;DR: A high-yield and high-throughput method is used to demonstrate nanometer-thin photodetectors with significantly enhanced light absorption based on nanocavity interference mechanism, which exhibit unique optoelectronic properties, such as the strong field effect and spectral selectivity.
Journal ArticleDOI
226 nm AlGaN/AlN UV LEDs using p-type Si for hole injection and UV reflection
Dong Liu,Sang June Cho,Jeongpil Park,Jiarui Gong,Jung-Hun Seo,Rafael Dalmau,Deyin Zhao,Kwangeun Kim,Munho Kim,Akhil Raj Kumar Kalapala,John D. Albrecht,Weidong Zhou,Baxter Moody,Zhenqiang Ma +13 more
TL;DR: In this article, the p-type Si NMs were used as both the hole injector and the reflective mirror to enhance light extraction efficiency (LEE) of a deep ultraviolet (UV) light-emitting diodes.
