Diode multipliers for submillimeter-wave InAlAs/InGaAs heterostructure monolithic integrated circuits
InAlAs/InGaAs heterostructures are studied as multiplier elements for submillimeter-wave monolithic integrated circuits. The designs considered for this purpose are based on the principle of conventional HEMT, HEMT with n+ bottom layer, and a new proposed scheme of quantum-confined modulated charge (QCMC). The QCMC diode is analyzed theoretically and experimentally showing its potential operation capability at 1.5 THz.
