Simulation of Removal of Surface-State-Related Lag and Current Slump in GaAs FETs

Hafiz H., Kumeno M., Horio K., Shibaura Institute of Technology, JP

Two-dimensional transient analysis of field-plate GaAs MESFETs is performed in which surface states are considered. Quasi-pulsed current-voltage curves are derived from the transient characteristics. It is shown that drain lag and current slump due to [...]

Simulation of Field-Plate Effects on Surface-State-Related Lag and Current Slump in GaAs FETs

Tanaka T., Itagaki K., Nakajima A., Horio K., Shibaura Institute of Technology, JP

In this study, we carry out two-dimensional transient analysis of field-plate GaAs MESFETs by taking surface states into account. Quasi-pulsed current-voltage curves are derived from the transient characteristics. We show that drain lag and current [...]

Simulation of Decrease in Lag phenomena and Current Slump of Field-Plate GaAs FETs

Itagaki K., Ueda H., Terao Y., Horio K., Shibaura Institute of Technology, JP

Two-dimensional transient analysis of field-plate GaAs MESFETs is performed in which a deep donor “EL2” and a shallow acceptor are considered in a semi-insulating substrate, and the results are compared between the two cases with [...]
