Patents by Inventor Jonathan Spanier

Jonathan Spanier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20160155941
    Abstract: A vertical charge ordered transistor is disclosed. A thin charge ordered layer is employed as a tunnel barrier between two electrodes. A gate-induced accumulation of charge destabilizes the charge ordered state around the circumference of the device, opening up a parallel ohmic conduction channel, which leads to an exponential increase in source-drain current. VCOT devices have the potential to exhibit very large on/off ratios, low off-state currents, and sub-threshold slopes below 60 mV/dec.

  • Publication number: 20060289761
    Abstract: Nanoscaled, tunable detector devices for ultrasensitive detection of terahertz (THz) radiation based on the fabrication of one-dimensional (1D) plasma devices having clouds of strongly correlated and spatially confined electronic charge carriers are disclosed. These one-dimensional collective excitations (“plasmons”) are realized using coaxial semiconducting core-shell nanowires or by electrostatically confining a two dimensional charge to one dimension. By exploiting the properties of plasmons confined to reduced dimensions and under a selected device configuration, conventional limitations on carrier drift and transit times that dictate the speed and sensitivity of transistors can be circumvented, and detector sensitivity can be improved. 1D devices with sub-picosecond response times will be important for a range of applications in diverse areas such as remote sensing and imaging, molecular spectroscopy, biotechnology, and in a range of the spectrum that has been difficult to detect.
