Just like with NPN and PNP transistors, there are N-FETs and P-FETs. N-FETs are like NPN transistors – the gate pin needs to have higher voltage than the source pin for the FET to open.

Wafer Maker is a fast-paced game where you are growing silicon crystals to make transistors ... The object is to create as many PNP or NPN sets as possible within the two-minute time limit ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

Another study focused on the electronic properties of defects formed at the SiO2/Si interface in gate-controlled lateral PNP transistors. It found that ionizing radiation creates two types of ...
