Abstract
This article reports the performance of alloyed Ohmic contacts to Ga(1 -X)In-(X)As/InP composite channel InP high electron mobility transisto rs for various indium compositions, from X=35% to X=81%. Both strained and pseudomorphic structures were utilized to observe the impact of t he indium concentration on electron mobility, carrier concentration, s heet resistance, and specific contact resistance. The lowest specific contact resistance (Rt<0.16 Ohm mm) was obtained for strained structur es with indium concentrations of 74% and 81%. For strained structures with indium concentrations of 35%, we observe specific contact resista nce of 0.35 Ohm mm. (C) 1997 American Vacuum Society. [S0734-211X(97)0 2105-7].
