In this work, we propose a novel enhancement-mode GaN metal-oxide-semiconductor high electron mobility transistor (MOS-HEMT) with a 10 nm T-gate length and a high-k TiO2 gate dielectric. The DC and RF characteristics of the proposed GaN MOS-HEMT structure are analyzed by using a TCAD Software. | Journal of Science Advanced Materials and Devices 4 2019 180e187 Contents lists available at ScienceDirect Journal of Science Advanced Materials and Devices journal homepage locate jsamd Original Article Design and analysis of 10 nm T-gate enhancement-mode MOS-HEMT for high power microwave applications Touati Zine-eddine a Hamaizia Zahra a Messai Zitouni b c a Laboratory of Semiconducting and Metallic Materials University of Mohamed Khider Biskra Algeria b Electronics Department Faculty of Sciences and Technology University of BBA Algeria c Laboratory of Optoelectronics and Components UFAS 19000 Algeria a r t i c l e i n f o a b s t r a c t Article history In this work we propose a novel enhancement-mode GaN metal-oxide-semiconductor high electron Received 17 December 2018 mobility transistor MOS-HEMT with a 10 nm T-gate length and a high-k TiO2 gate dielectric. The DC and Received in revised form RF characteristics of the proposed GaN MOS-HEMT structure are analyzed by using a TCAD Software.
