1950's PNP Transistors by General Electric. TOP ROW (L-R): 2N43, 2N44, 2N45, 2N107 and 2N188A BOTTOM ROW: 2N107, 2N191 and 2N241. The 2N107 is an early germanium alloy junction PNP transistor developed by General Electric (GE) in 1955, to become GE's entry into the electronic hobbyist market successfully started with the CK722 transistor.
Geary County is a county located in the U.S. state of Kansas.Its county seat and most populous city is Junction City. [4] As of the 2020 census, the county population was 36,739. [2]
SiGe (/ ˈ s ɪ ɡ iː / or / ˈ s aɪ dʒ iː /), or silicon–germanium, is an alloy with any molar ratio of silicon and germanium, i.e. with a molecular formula of the form Si 1−x Ge x. It is commonly used as a semiconductor material in integrated circuits (ICs) for heterojunction bipolar transistors or as a strain-inducing layer for CMOS ...
An ohmic contact is a non-rectifying electrical junction: a junction between two conductors that has a linear current–voltage (I–V) curve as with Ohm's law.Low-resistance ohmic contacts are used to allow charge to flow easily in both directions between the two conductors, without blocking due to rectification or excess power dissipation due to voltage thresholds.
Whether a given metal-semiconductor junction is an ohmic contact or a Schottky barrier depends on the Schottky barrier height, Φ B, of the junction. For a sufficiently large Schottky barrier height, that is, Φ B is significantly higher than the thermal energy kT , the semiconductor is depleted near the metal and behaves as a Schottky barrier .
Esophagogastric junction outflow obstruction (EGJOO) is an esophageal motility disorder characterized by increased pressure where the esophagus connects to the stomach at the lower esophageal sphincter. EGJOO is diagnosed by esophageal manometry.

Gap junction proteins include the more than 26 types of connexin, and at least 12 non-connexin components that make up the gap junction complex or nexus. [4] These components include the tight junction protein ZO-1 —a protein that holds membrane content together and adds structural clarity to a cell, [ 5 ] sodium channels , [ 6 ] and aquaporin .
