Latest Patents

Ralston's latest patents include innovative methods for the selective intermixing of layered structures composed of thin solid films. One of his patents focuses on synthetic layered structures, which may be semiconductor structures, modified both laterally and vertically to provide novel electronic, optoelectronic, and optical properties. This is achieved through selective intermixing using laser beam or electron beam energy sources, allowing interaction between neighboring regions without causing physical damage to the layered structures. Another patent describes a method for selectively intermixing multilayer structures formed of different materials, enabling a compositionally transmuted structure where the distinction between the original materials is lost, at least partially. This intermixing is accomplished through irradiation with a pulsed or rapidly scanned laser or electron beam, enhancing the degree of intermixing with multiple pulses.
