A four-terminal Hall bar configuration is commonly used in the investigation of transport properties of modulation doped heterostructures. Here it is found that a single Hall bar can act as a multifunction logic gate if a gate electrode is patterned between the voltage probes. Four different logic functions can be obtained depending on the input voltage levels. Operation of all logic gates is demonstrated and merits of such gates with respect to conventional logic gates are discussed.

Abstract
A four-terminal Hall bar configuration is commonly used in the investigation of transport properties of modulation doped heterostructures. Here it is found that a single Hall bar can act as a multifunction logic gate if a gate electrode is patterned between the voltage probes. Four different logic functions can be obtained depending on the input voltage levels. Operation of all logic gates is demonstrated and merits of such gates with respect to conventional logic gates are discussed.File in questo prodotto:
