Crystalline AlN Interfacial Layer on GaN Using Plasma-Enhanced Atomic Layer Deposition
Autor: Il-Hwan Hwang, Myoung-Jin Kang, Ho-Young Cha, Kwang-Seok Seo
Publikováno v: Crystals, Vol 11, Iss 4, p 405 (2021)
In this study, we report on the deposition of a highly crystalline AlN interfacial layer on GaN at 330 °C via plasma-enhanced atomic layer deposition (PEALD). Trimethylaluminum (TMA) and NH3 plasma were used as the Al and N precursors, respectively.

Effect of Dietary Lysophospholipid (LIPIDOL™) Supplementation on the Improvement of Forage Usage and Growth Performance in Hanwoo Heifer
Autor: Il Hwan Hwang, Wan-Sun Song, Jinho Yang, Nag-Jin Choi, Sangbuem Cho
Publikováno v: Journal of The Korean Society of Grassland and Forage Science. 35:232-237
The present study investigated the effects of Lysophospholipid (LPLs, LIPIDOL™) on the growth performance and nutrient digestibility of Hanwoo heifers. A feeding trial was performed for 120 days until slaughter using a herd of 24 Hanwoo heifers. Ei

High-performance normally off AlGaN/GaN-on-Si HEMTs with partially recessed SiN x MIS structure
Autor: Gwang-Ho Choi, Kwang-Seok Seo, Myoung-Jin Kang, Ho-Young Cha, Il-Hwan Hwang, Minseong Lee
Publikováno v: physica status solidi (a). 214:1600726
Recessed MIS gate structures with SiNx gate dielectric layer were investigated for use in normally off AlGaN/GaN-on-Si high electron mobility transistors (HEMTs). The channel mobility and threshold voltage (Vth) instability were strongly affected by
