Air conditioning is required. Retrieved July 28, Al—Si junction refers to the high-speed aluminum—silicon metal—semiconductor barrier diode, commonly known as a Schottky diode. The transistor consists two PN diode connected back to back. A controversy developed inhowever, over the patentability of ENIAC's basic digital concepts, the claim being made that another U. Most transistors include three connection points, or terminals, which can connect to other transistors or electrical components. This temperature should not be exceeded or the transistor may be damaged. Nanodevices for Photonics and Electronics: Advances and Applications.
