S. Bollaert et al., DESIGN, FABRICATION, AND CHARACTERIZATION OF STRIPED CHANNEL HEMTS, I.E.E.E. transactions on electron devices, 41(10), 1994, pp. 1716-1724
A theoretical and experimental study of striped channel HEMT's is pres
ented in this paper. The source to drain region of striped channel HEM
T's is divided into a number of narrow conducting channels. Hence, the
control of the charges by the Schottky gate is two-dimensional, which
improves the transconductance value. Striped channel HEMT's have been
successfully realized and characterized. The experimental results agr
ee well with the theoretical ones. The structure of an optimized devic
e is then proposed.
