WebbA homojunction PN junction.The band at the interface is continuous. In forward bias mode, the depletion width decreases. Both p and n junctions are doped at a 1e15/cm3 doping level, leading to built-in potential of ~0.59 V. Observe the different Quasi Fermi levels for conduction band and valence band in n and p regions (red curves). WebbRussell Shoemaker Ohl (January 30, 1898 – March 20, 1987) was an American scientist who is generally recognized for patenting the modern solar cell (U.S. Patent 2,402,662, "Light sensitive device"). Ohl was a notable semiconductor researcher prior to the invention of the transistor. He was also known as R.S. Ohl. Russell Ohl’s specialized area of …
