The PI's wish to fabricate new types of modulation doped field-effect           transistors (MODFETs).  A very high density of electrons will be                supplied from a selectively doped n-A1GaAs/GaAs (60-100A)/n-A1GaAs              double-heterojunction rectangular well structure grown by molecular             beam epitaxy.  The A1 mole fraction (x) to be used in these devices             will be less than the conventional value of 0.3.  It is expected that           the reduction in x will avoid the persistent trapping effects, normally         observed in these devices at cryogenic temperatures, without                    sacrificing the device performance.  The dimensions and the doping              concentration will be chosen to achieve a high transconductance and a           large current swing.
