... All solid-state electronic and opto-electronic devices are based on doped semiconductors. In many devices the doping and hence the carrier concentrations are non-homogeneous. In the following section we will consider the p-n junction which is an important part of many semiconductor devices and which ...

... the transistor, introduction (pnp) In broad terms is the fkn as follows, The Emitter injecting minority carriers (holes) in the base, hopefully recombines the holes not in too large amount with electrons entering the base, instead diffuses the hole towards to the collector. The collector is reverse ...

Topic 7 | The Cathode-Ray Tube
... Topic 7 | The Cathode-Ray Tube Let’s look at how the concept of potential is applied to an important class of devices called cathode-ray tubes, or “CRTs” for short. Cathode-ray tubes are found in oscilloscopes, and similar devices are used in TV picture tubes and computer displays. The name goes bac ...
