Title: Innovations of Uri Sivan in Semiconductor Technology
Introduction
Uri Sivan is a notable inventor based in Yorktown Heights, NY (US). He has made significant contributions to the field of semiconductor devices, particularly in the area of electron wave manipulation. His innovative work has led to the development of a unique patent that addresses the behavior of ballistic electrons in doped semiconductor elements.
Latest Patents
Uri Sivan holds a patent titled "Electron wave deflection in modulation doped and other doped." This invention relates to semiconductor devices that incorporate doped semiconductor elements or modulation doped devices. The patent describes how ballistic electrons in these elements or in a two-dimensional electron gas (2-DEG) can be deflected by shaped potential barriers. A shaped potential barrier is created by depositing a shaped electrode on the surface of the device and applying a potential to it. The electrode can take the form of a biconcave lens, which induces a corresponding potential barrier in the underlying device. As electrons transit this potential barrier, their phases differ across the width of the electrode, resulting in a focused beam of electrons. By adjusting the applied potential, the focal point of the exiting electrons can be moved parallel to the axis of the lens-like electrode. Other configurations, such as a biconvex shape, can cause incident electrons to diverge from their original paths. Additionally, a triangular electrode can reflect, transmit, or deflect incident electron waves depending on the applied potentials.
