Abstract : 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 (1 DES). We expect this system to be particularly sensitive to infrared radiation just at the crossover from a 2DES to a IDES.
