11. Electronic components employing rectifying junctions include p n diodes, Schottky diodes and bipolar junction transistors . 12. In bipolar junction transistors , the emitter current is the sum of the collector and base currents. 13. Silicon junction transistors were much more reliable than vacuum tubes and had longer, indefinite, service life. 14. There were several types of improved alloy-junction transistors developed over the years that they were manufactured. 15. The 2N43-45 series was GE's first commercial alloy junction transistor using the 2N numbering system. 16. A bipolar junction transistor with a Schottky barrier between the base and the collector is known as a Schottky transistor. 17. By the 1960s the improved switching speed of bipolar junction transistors had allowed for high frequency DC / DC converters. 18. For this reason, alternate technologies such as Resonant Tunneling Diodes and Neuron-Bipolar Junction Transistors are being explored. 19. Grown-junction transistors rarely operated at frequencies above the audio range, due to their relatively thick base layers. 20. Shockley eventually infuriated and alienated Bardeen and Brattain, and he essentially blocked the two from working on the junction transistor .
