Title: Weng Y Leong: Innovator in Semiconductor Quantum Wires
Introduction
Weng Y Leong is a notable inventor based in Worcestershire, GB. He has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. His work primarily focuses on the development of silicon quantum wires, which have promising applications in various electronic devices.
Latest Patents
One of Weng Y Leong's latest patents involves a method of making semiconductor quantum wires. This method employs a semiconductor wafer as the starting material. The wafer is weakly doped p-type with a shallow heavily doped p layer for current flow uniformity purposes. It is anodized in 20% aqueous hydrofluoric acid to produce a layer that is microns thick with 70% porosity and good crystallinity. The layer is subsequently etched in concentrated hydrofluoric acid, which provides a slow etch rate. This etching process increases porosity to a level of 80% or above. At this level, pores overlap, and isolated quantum wires are expected to form with diameters less than or equal to 3 nm. The etched layer exhibits photoluminescence emission at photon energies well above the silicon bandgap (1.1 eV) and extends into the red region (1.6-2.0 eV) of the visible spectrum.
