Latest Patents

One of her latest patents is titled "Electron transmissive window usable with high pressure electron spectrometry." This invention describes a vacuum window that transmits keV electrons and is applicable for high-pressure electron analysis, such as X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). The design allows for the sample to be positioned outside the ultra-high vacuum (UHV) analyzer chamber, potentially in a controlled gas environment. The window features a grid formed from a support layer and a thin window layer, with a thickness of approximately 2 to 3 nanometers. This innovative window design enables compact and user-friendly electron analyzers while allowing control of the gas environment at the sample surface during analysis.

Another significant patent is "Growth of delta-doped layers on silicon CCD/S for enhanced ultraviolet." This invention focuses on the backside surface potential well of a backside-illuminated CCD, which is confined to within about half a nanometer of the surface. This is achieved through molecular beam epitaxy (MBE) to grow a delta-doped silicon layer on the back surface. The process creates an extremely sharp dopant profile, resulting in a high electric field that confines the backside surface potential well. This advancement leads to nearly 100% internal quantum efficiency throughout the UV wavelength range, with stable quantum efficiency.
