Popis: This paper proposes a $hbox In_0.5hbox Al_0.5$ As/ $hbox In_xhbox Ga_1-xhbox As$break / $hbox In_0.5hbox Al_0.5hbox As$ $(x=0.3-0.5-0.3)$ metamorphic high-electron mobility transistor with tensile-strained channel. The tensile-strained channel structure exhibits significant improvements in dc and RF characteristics, including extrinsic transconductance, current driving capability, thermal stability, unity-gain cutoff frequency, maximum oscillation frequency, output power, power gain, and power added efficiency.
