"utilize carriers' excess kinetic energy, improving transistors' speed/ functionality... generated via stimulated emission of heated carriers... low power, multifunctional hot-emitter transistor of 2 coupled graphene/ germanium Schottky junctions... germanium injects high-energy carriers into graphene base, diffusing to emitter, triggering increased current  due to the preheated carriers there, enabling sub-threshold swing <1 mV/dec, peak-to-valley room temperature current ratio >100... multi-valued logic computing"
