Semiconductors are at the heart of most electronics. ... silicon, and germanium, are intrinsic semiconductors due to the ...

Most proposed monolayer transistors based on 2D semiconductors were created using a few carefully selected materials known to have relatively stable lattice structures, such as graphene, tungsten ...

This contraption was the very first semiconductor amplifier, because when a bit of current came through one of the gold contacts, another even stronger current came out the other contact. Here's why ...

CRYSTAL rectifiers, the essential constituents of which are a metal and semiconductor in contact, are of two types, large-area contact rectifiers, such as copper oxide or selenium rectifiers, and ...

Germanium. Like gallium, germanium wafers can be used as substitutes for silicon in semiconductor technology. Germanium, too, boasts greater thermal resistance, making germanium-based chips suitable ...

China just fought back in the semiconductor exports war. Here’s what you need to know. The country aims to restrict the supply of gallium and germanium, two materials used in computer chips and ...

Just one month after China announced it would curb exports of germanium and gallium, both essential for making semiconductors, its overseas shipments of the materials fell to zero.

A semiconductor is a material or device that only conducts electricity under certain conditions. Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic ...
