The transistor transistor transistor became a popular product which is a major component of transistor radio in the 1940 's. Everyone wants them to have them, and all the scientists want me to know how to use it to make a profit for them. John Bardeen, Bill Shockley, and Walter Brittian are the three major scientists created by transistors. Bill Shockley, born in California, is a good person in this paper, but I can not understand how to make it and how to make it. Walter Bridrian, on the other hand, is basically an excellent scientist who can do whatever he thinks.
There are also two kinds of transistors called bipolar junction transistor (BJT) and field effect transistor (FET). The transistor we talked about is BJT type. These types are not explained in detail. It is out of range. A very basic concept of transistors is sufficient for our work of building 1 bit memory. If there is no voltage on the base, you can see that the current does not flow from C to E, that is, the transistor is turned off at this point. However, if the base has a positive voltage, the transistor turns on. Let's create a NAND gate with two transistors. A NAND gate is one of the most important logic gates because all other gates (OR, NOT, AND, etc.) can be constructed using these NAND gate combinations.
A bipolar junction transistor (bipolar transistor or BJT) is a transistor that uses electron and hole charge carriers. In contrast, unipolar transistors such as field effect transistors use only one type of charge carriers. For their operation, the BJT uses two semiconductor types, two junctions between n-type and p-type. By convention, the direction of the current on the graph is shown as the direction in which the positive charge travels. This is called conventional current. However, the current in many metal conductors is due to the flow of electrons and they are negatively charged, so they move in the opposite direction to the conventional current. On the other hand, inside the bipolar transistor, the current can be composed of positively charged holes and negatively charged electrons. In this paper, the current arrow is shown in the normal direction, but the moving labels of holes and electrons indicate the actual direction in the transistor.
