Latest Patents

One of Yang's latest patents is the "Enhancement mode single electron transistor." This invention features a transistor that includes a bottom dielectric layer, a first layer, a second layer, a top dielectric layer, and a gate electrode. The first and second layers create a composite quantum well situated between the bottom and top dielectric layers. The configuration allows for the formation of a hole wire in the first layer, with the gate electrode positioned over a portion of the hole wire, effectively dividing the top dielectric layer into a source contact and a drain contact.

Another significant patent is the "Nanofabrication of InAs/A1Sb heterostructures." This patent describes a heterostructure that consists of a buffer layer, a bottom barrier layer, a quantum well layer, a top barrier layer, and a p-doped cap layer. A portion of the cap layer is etched to create conducting electrons in the quantum well layer beneath the etched area. The method of etching involves providing a heterostructure and an etchant solution made of acetic acid, hydrogen peroxide, and water, which is then applied to the heterostructure for etching.
