Free-standing Al[subscript x]Ga[subscript 1−x]As heterostructures by gas-phase etching of germanium

We outline a facile fabrication technique for the realization of free-standing Al[subscript x]Ga[subscript 1−x]As heterostructures of arbitrary aluminum content. Utilizing xenon difluoride (XeF[subscript 2]) we rapidly and selectively remove a sacrificial germanium (Ge) underlayer in a room temperat...
