Dimensionally Self Regulating Materials.

Abstract

Statement of Problem Studied and Results: This is a collaborative project between the University of Oklahoma (OU) and Boston University (BU) studying the possibility of producing an infrared detector which integrates the function of a spectrometer. The successful implementation of these ideas could lead to a smart infrared detector. The system we are studying as a prototype is the two-dimensional electron system (2DES) GaAs-AlGaAs modulation-doped heterostructure system patterned with very narrow gates. This leads to a transition to an one-dimensional electron system (1DES). We expect this system to be particularly sensitive to infrared radiation just at the crossover from a 2DES to a 1DES. Thus this system is a Dimensionally Self-Regulating Material. We have made considerable progress toward these goals. We have made successful theoretical models of the proposed devices and we have produced and tested the first generation devices electrically. Far-infrared tests are now in progress. jg
