Still, modern manufacturing is dominated by two basic types of semiconductors: N-type and P-type. Like carbon, silicon has four electrons in its outermost electron shell, so it can form four bonds.

Two slices of N-type semiconductor, the emitter and the collector, form a sandwich with a layer of P-type semiconductor, called the base. P- and N-type semiconductors are made with different ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

A recent article in Nature Communications introduced a method for precise p- and n-type substitutional doping of two-dimensional (2D) semiconductors. This method was applied for the one-step ...

What is the principle of CMOS technology? The principle of CMOS technology is to use a combination of n-type and p-type metal-oxide-semiconductor field effect transistors (MOSFETs) to implement logic ...

Firstly, the researchers processed 2D semiconductors using well ... we are working on extending this approach to p-type 2D transistors (as opposed to the n-type devices used in this study ...
