QuestionAnswer
Two common semiconductor materials are ? and ? . silicon / germanium
In an atom that has lost an electron, the place vacated by the free electron is referred to as a(n) ? . hole
A(n) ? exhibits characteristics of both insulators and conductors. semiconductor
Adding impurities to a pure material is known as the ? process. doping
A semiconductor material with an excess of free electrons is called a(n) ? material. N-type
Excess electrons can be added to intrinsic silicon or germanium by adding impurities such as ? , ? , and ? . antimony / arsenic / bismuth
A semiconductor material with a deficiency of free electrons is called a(n) ? material. P-type
Adding gallium, boron, or indium to pure silicon or germanium will create a material with an excess of ? . holes
The area between the P-type materials and the N-type materials of a single junction PN diode is known as the ? region. depletion
The P side of a PN junction diode is referred to as the ? . anode
The N side of a PN junction diode is referred to as the ? . cathode
The negative and positive ions in the depletion region of a silicon diode creates an interior ? voltage of approximately 0.6 volts. barrier
To conduct current, the semiconductor diode must be ? biased. forward
t/f When a diode is properly biased to conduct, the depletion region will expand. false
A diode is forward biased when the cathode is connected to the ? side of the external voltage source and the anode is connected to the ? side. negative / positive
When properly biased, a silicon diode will conduct when more than ? is applied. 0.6 V
t/f When the width of the depletion region changes, in essence the resistance of the PN junction changes. true

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
