Question
Answer
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
🗑
The area between the P-type materials and the N-type materials of a single junction PN diode is known as the ? region.   show
🗑
show anode  
🗑
show cathode  
🗑
show barrier  
🗑
show forward  
🗑
show 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.   show
🗑
show 0.6 V  
🗑
t/f When the width of the depletion region changes, in essence the resistance of the PN junction changes.   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
