NUMERICAL SIMULATION OF THE FUNCTION OF SCIENTIFIC INSTRUMENTATION FOR MEASURING THE SPEED OF ELECTRON DEVICES

ONE OF THE KEY ISSUES FACING ELECTRONIC DEVICES IS DETERMINING THEIR SPEED. THEORY PREDICTS THAT NONEQUILIBRIUM EFFECTS IN DEVICES SHOULD IMPROVE THE SPEED OF SOME DEVICES BY UPWARDS OF A FACTOR OF FIVE. THE DIFFICULTY LIES IN FINDING NONEVASIVE EXPERIMENTAL TECHNIQUES THAT ISOLATE THIS PHENOMENA, PARTICULARLY WHEN CHARGE REARRANGEMENT (CAPACITIVE EFFECTS) IN DEVICES OCCUR ON TIME SCALES THAT APPROACH THE SPEEDS BEING SOUGHT. THIS DOCUMENT DESCRIBES THE FIRST APPLICATION OF NUMERICAL SIMULATION PROCEDURES TO ASSIST IN FINDING NONEVASIVE SCIENTIFIC INSTRUMENTATIVE FOR MEASURING THE SPEED OF ELECTRONIC DEVICES. IN THIS PHASE I PROGRAM THE FEASIBILITY OF PERFORMING THESE STUDIES IS TO BE ESTABLISHED THROUGH NUMERICAL SIMULATIONS THAT SCRUTINIZE AUSTONS TECHNIQUE FOR MEASURING THE RESPONSE OF ELECTRON DEVICES. THE DEVICES TO WHICH THIS SIMULATION IS TO BE APPLIED ARE TWO NEW DEVICES, THE VERTICAL HEMT AND THE PSEUDO-MORPHIC HEMT.
