Analysis of Breakdown Voltage of AlGaN/GaN HEMTs with High-k Passivation Layer and High Acceptor Density in Buffer Layer

Ueda S., Tomita R., Kawada Y., Horio K., Shibaura Institute of Technology, JP

AlGaN/GaN HEMTs are now receiving great interest for application to high-power microwave devices and high power switching devices. To improve the breakdown voltage, the introduction of field plate is shown to be effective, but it [...]

Analysis of Breakdown Characteristics in Field-Plate AlGaN/GaN HEMTs: Dependence on Deep-Acceptor Density in Buffer Layer

Akiyama S., Kondo M., Wada L., Horio K., Shibaura Institute of Technology, JP

We make a two-dimensional analysis of field-plate AlGaN/GaN HEMTs with a Fe-doped semi-insulating buffer layer, and studied how the deep-acceptor density in the buffer layer NDA and the field-plate length LFP affect the breakdown voltage [...]

Analysis of Gate-Length Dependence of Lags and Current Collapse in Field-Plate AlGaN/GaN HEMTs

Chiba T., Saito Y., Tsurumaki R., Horio K., Shibaura Institute of Technology, JP

We make 2-D transient simulations of field-plate AlGaN/GaN HEMTs with a semi-insulating buffer layer, where a deep acceptor above the midgap is considered. We particularly study how the gate lag, drain lag and current collapse [...]

Molecular Dynamics Simulation Study on Nanoelectromechanical Oscillator based on Graphene Nanoflake

Kwon O-K., Kang J-W, Semyung University, KR

Recently graphene has also been highlighted as an ideal lubricant for microelectromechanical systems (MEMSs) and nanoelectromechanical systems (NEMSs), where ‘traditional’ lubricants no longer function normally. Atomic-scale graphene can be fabricated using micro- mechanical chop crack, [...]
