Abstract
Gateless AlGaN/GaN high electron mobility transistor (HEMT) structures exhibit large changes in source-drain current upon exposing the gate region to various block co-polymer solutions. The polar nature of some of these polymer chains lead to a change of surface charges in gate region on the HEMT, producing a change in surface potential at the semiconductor/liquid interface. The nitride sensors appear to be promising for a wide range of chemical gas, combustion gas, liquid and strain sensing.
