_____ is the field of technology the deals with the control of electron flow.

Electronic _____ are devices that are used to control electron flow.

Electronic components are grouped together to for electronic _____.

A _____ is a type of semiconductor that's often used in circuits as a rectifier.

A _____ changes AC current to DC current.

A _____ is a material or device that conducts current flow "part-time". That is, sometimes this device acts like a conductor, and sometimes an insulator.

The two main types of semiconductors are _____ and _____.

The most important semiconductor materials used are the elements ____(Ge), ____(Si), and ____(Se), and the compound ____(GaAs).

The _____ atom is the simplest atom known. It has 1 proton and 1 electron.

Atoms that have 8 electrons in their outer shell are called ____ atoms.

Examples of inert atoms are argon, helium, neon, krypton, and xenon. These elements are sometimes called ____ gases or ____ gases. Atoms of these elements are very stable and don't combine easily with other atoms.

The sharing of electrons between atoms is called __________.

At room temp., a few electrons will always break from their bonds and move for a short time around a semiconductor material. This random motion of electrons is called _____ current, and it can be seen in all semi.c. materials.

To make a semi.c. that has certain desired properties, certain atoms of other substances are added to the latticework structure of a crystal as it grows. These added atoms are impurities called _____.

The process of adding dopants to a semiconductor material is called _____.

If the dopant added to a material has 5 electrons in its outer shell, it's called a ____. If the dopant has 3 electrons in its outer shell, it's called an _____.

When donor atoms are added to a pure material, a semiconductor called an _____ material is produced.

When acceptor atoms are added to a pure material, a semiconductor called _____ material is produced.

A _____ is the absence of an electron in an atom.

N-type material has excess _____, and P-type material has excess _____.

In N-type semi.c. materials, electrons dominate current flow. So the electrons are called _____-charge carriers.

Any holes that appear in an N-type semi.c. material are called _____-charge carriers.

The direction of electron flow in a/an _____ material is from negative to positive.
