ALEXANDRIA, Va., Oct. 4 -- International Business Machines, Armonk, N.Y., has been assigned a patent (8,541,734) developed by Solomon Assefa, Ossining, N.Y., Yurii A. Vlasov, Katonah, N.Y., and Fengnian Xia, Plainsboro, N.J., for an "avalanche impact ionization amplification devices."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A semiconductor photodetector may provide charge carrier avalanche multiplication at high field regions of a semiconductor material layer. A semiconductor current amplifier may provide current amplification by impact ionization near a high field region. A plurality of metal electrodes are formed on a surface of a semiconductor material layer and electrically biased to produce a non-uniform high electric field in which the high electric field strength accelerates avalanche electron-hole pair generation, which is employed as an effective avalanche multiplication photodetection mechanism or as an avalanche impact ionization current amplification mechanism."
The patent application was filed on Sept. 5, 2012 (13/603,567). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,541,734.PN.&OS=PN/8,541,734&RS=PN/8,541,734
