Development of high-frequency SiC-MESFETs

Electronics and Communications in Japan (Part II: Electronics), 2003

We have developed high power SiC-MESFETs for high-freqeuncy applications. We obtained a cutoff freqeuncy of 9.3 GHz and a maximum oscillation frequency of 34.2 GHz from a 0.5 µm gate MESFET. We measured pulsed output power characteristics of 54.1 W at 1.0 GHz and 11.2 W at 9.4 GHz from a 39.2mm-gate-MESFET and a 9.6mm-gate-width MESFET, respectivly.

The Review of Laser Engineering Topical Papers on Thin Films Fabrication and Control. Laser Atomic Layer Epitaxy

The Review of Laser Engineering, 1996

Laser atomic layer epitaxy technique is reviewed, and growth characteristics and surface processes in laser Atomic Layer Epitaxy (ALE) are described. The self-limiting mechanism is the key to attain the ideal layer-by-layer controllability in growth rate. The self-limited growth is obtained in a wide range of several growth parameters. The self-limiting mechanism is induced by the site-selective decomposition of alkylgallium precursors (alkylgallium precursors decompose only at the As surface, but not at the Ga surface), and the direct absorption of laser light in the chemisorbed alkylgallium layer provides the site selectivity.
