With a total of 5 patents to his name, Canham's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Canham's latest patents focuses on a method of making semiconductor quantum wires. This method employs a semiconductor wafer as the starting material, which is weakly doped p-type with a shallow heavily doped p layer for current flow uniformity. The wafer is anodized in 20% aqueous hydrofluoric acid to produce a layer that is microns thick with 70% porosity and good crystallinity. Following this, the layer is etched in concentrated hydrofluoric acid, which provides a slow etch rate. This etching process increases porosity to a level of 80% or above, allowing for the formation of isolated quantum wires with diameters less than or equal to 3 nm. The etched layer exhibits photoluminescence emission at photon energies well above the silicon bandgap, extending into the red region of the visible spectrum.
