Abstract: A wafer includes a substrate and at least one intermediate layer formed on a surface of the substrate. The at least one intermediate layer covers the surface of the substrate at least partially. An outer surface of the at least one intermediate layer is directed away from the surface of the substrate. The wafer further includes nanostructures grown on the outer surface of the at least one intermediate layer. The at least one intermediate layer is formed in such a way that positions of growth of the nanostructures are predetermined on the outer surface of the at least one intermediate layer. At least one nanostructure material of the nanostructures is assembled at the positions of growth of the nanostructures.

Abstract: A novel unipolar transistor device has been realized starting from two-dimensional electron systems (2DES) in modulation-doped AlGaAS/GaAs heterostructures. A 600 nm wide 1D channel is insulated laterally from 2DES regimes by 700 nm wide deep mesa etched trenches. The conductivity in the quasi-one-dimensional channel can be tuned via the in-plane lateral-field effect of the adjacent 2DES-gates where the vacuum (or air) in the etched trenches serves as the dielectric. Room temperature operation is demonstrated yielding a 161S transconductance corresponding to 160 mS/mm 2D transconductance.
