Two common semiconductor materials are ? and ? . | show 🗑
|
||||
In an atom that has lost an electron, the place vacated by the free electron is referred to as a(n) ? . | show 🗑
|
||||
A(n) ? exhibits characteristics of both insulators and conductors. | show 🗑
|
||||
Adding impurities to a pure material is known as the ? process. | show 🗑
|
||||
A semiconductor material with an excess of free electrons is called a(n) ? material. | show 🗑
|
||||
Excess electrons can be added to intrinsic silicon or germanium by adding impurities such as ? , ? , and ? . | show 🗑
|
||||
A semiconductor material with a deficiency of free electrons is called a(n) ? material. | show 🗑
|
||||
Adding gallium, boron, or indium to pure silicon or germanium will create a material with an excess of ? . | show 🗑
|
