Tae-Hyeon Kil,Tae-Hyeon Kil,Sanghyeon Kim,Jeong Daehan,Dae-Myeong Geum,Dae-Myeong Geum,Sooseok Lee,Sung-Jin Jung,Sung-Jin Jung,Sangtae Kim,Chan Park,Jin-Sang Kim,Jeong Min Baik,Ki-Suk Lee,Chang Zoo Kim,Won Jun Choi,Seung Hyub Baek,Seung Hyub Baek +17 more
TL;DR: In this article, a concentrating photovoltaic/thermoelectric hybrid generator using a single-junction, GaAs-based solar cell and a conventional thermoelectoric module as a model system was demonstrated.
Journal ArticleDOI
Ultra-high-throughput Production of III-V/Si Wafer for Electronic and Photonic Applications.
Dae-Myeong Geum,Dae-Myeong Geum,Min-Su Park,Ju Young Lim,Hyun-Duk Yang,Jin Dong Song,Chang Zoo Kim,Euijoon Yoon,Sanghyeon Kim,Won Jun Choi +9 more
TL;DR: New concepts for an ultra-high-throughput heterogeneous integration of high-quality III-V films on the Si using the wafer bonding and epitaxial lift off (ELO) technique are reported, which leads to a dramatic cost reduction.
Journal ArticleDOI
Strategy toward the fabrication of ultrahigh-resolution micro-LED displays by bonding-interface-engineered vertical stacking and surface passivation
Dae-Myeong Geum,Seong Kwang Kim,Chang-Mo Kang,Seung-Hyun Moon,Jihoon Kyhm,Jae-Hoon Han,Dong-Seon Lee,Sanghyeon Kim +7 more
TL;DR: The obtained results clearly demonstrated that performance improvements could be possible by employing optimal passivation techniques by diminishing the pixel size for fabricating low-power and highly efficient microdisplays.
Journal ArticleDOI
Fabrication of high-quality GaAs-based photodetector arrays on Si
Sanghyeon Kim,Dae-Myeong Geum,Dae-Myeong Geum,Min-Su Park,Hosung Kim,Jin Dong Song,Won Jun Choi +6 more
TL;DR: In this article, the authors report on fabrication and characterization of high-quality 32 × 32 GaAs photodetector arrays on Si substrates fabricated by wafer bonding and epitaxial lift-off (ELO) techniques.
Journal ArticleDOI
Bioinspired Photoresponsive Single Transistor Neuron for a Neuromorphic Visual System
Joon-Kyu Han,Dae-Myeong Geum,Mun-Woo Lee,Ji-Man Yu,Seong Kwang Kim,Sanghyeon Kim,Yang-Kyu Choi +6 more
TL;DR: This study introduces a photoresponsive neuron device composed of a single transistor, developed by engineering an artificial neuron that responds to light, just like retinal neurons.
