Latest Patents

One of Wieck's latest patents describes a method of generating active semiconductor structures using a unipolar electronic component. This component features a quasi-one-dimensional carrier channel that exhibits all the characteristics of a field-effect transistor (FET). The design allows for simple production, self-alignment, and linear gates with low capacity, enabling very high operating frequencies. The structure is based on a homogenous 2D-layer with high carrier mobility, formed through the epitaxy of materials such as GaAs. Focused ion implantation is used to locally destroy the conductivity of the electron layer, creating insulating regions that remain stable at low and room temperatures. This innovative approach allows for the subdivision of the 2D-carrier layer into three insulated regions, with a tunable channel width controlled by gate potentials.

Another notable patent involves a novel unipolar transistor device realized from two-dimensional electron systems (2DES) in modulation-doped AlGaAS/GaAs heterostructures. This device features a 600 nm wide 1D channel insulated laterally from the 2DES regimes by deep mesa etched trenches. The conductivity in the channel can be adjusted via the in-plane lateral-field effect of the adjacent 2DES-gates, demonstrating room temperature operation with impressive transconductance values.
