Saptarshi Das, Ackley Professor of Engineering Science and Mechanics have developed high performance p-type field effect transistors (FETs) based on 2D materials. These transistors, introduced in ...

Bardeen, Brattain and Shockley had tested various combinations of p-type and n-type semiconductors under different conditions until they finally found a configuration that would allow a thin layer of ...

The outer layers had to be a semiconductor with either too many electrons (known as N-type) or too few (known as P-type), while the inner layer was the opposite. Under Shockley's prodding ...

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 ...

so these semiconductors are called positive-type or P-type. When a semiconductor includes both N-type and P-type materials, it is called a complementary metal-oxide semiconductor (CMOS ...

CMOS technology uses two different types of transistors, n-type (nMOS) and p-type (pMOS), which work together in pairs in a complementary manner. The term "complementary" refers to how these two ...

The use of n-type and p-type silicon is a foundation concept in the design of transistors. Pure silicon is not conductive. However, it can be made conductive by adding other elements to its ...

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 ...
