Standby energy losses are reduced by application of threshold switches. A typical voltage-controlled threshold switch remains in a state of low conductance until reaching a specific value of applied potential, above which it becomes highly conducting. This function is sometimes called bistability, or negative differential resistance (NDR). For voltage controlled threshold switches, many types of materials may be used in their fabrication, including the chalcogenides (periodic table VIa elements including Se and Te), other types of non-crystalline or amorphous glasses, various III-V semiconductors and compound semiconductors including GaN, and organic semiconductors. Application to one of today’s most pressing problems with increasing standby losses in ultra large scale integrated circuits (ULSI) is explained.
