CHAPTER 1 (Semiconductor Diodes)
An electronic device that operates when electrons move within a solid piece of semiconductor
The resistance to electrical current flow decreases as temperature increases.
Commercial products, industry, and all branches of the armed services.
Three to four times.
Solid, liquid, and gaseous.
Electrons, protons, and neutrons. The electron holds a negative charge, the proton holds a
positive charge, and the neutron holds no electrical charge.
A valence shell.
An atom that has more than its normal amount of electrons and which acquires a negative
Conduction band and valence band.
The width of the forbidden band or the separation between the conduction and valence bands.
The number of electrons in its valence shell.
Electron current flow.
To increase the number of free charges that can be moved by an external applied voltage.
When added to a semiconductor material.
Any donor impurity having five valence electrons in its outer shell.
Makes use of the rectifying properties of a PN junction to convert AC into DC by permitting
current flow in only one direction.
