Question

Silicon is an excellent element to use in computers based on the properties of the element.
Which of the following is NOT a property of silicon as applied to use in computer?

• A. Silicon can form a three-dimensional structure similar to a diamond giving the substance strength.
• B. The conductivity of a semiconductor increases with increased temperature without a substantial increase in heat.
• C. Silicon can be bonded to form either a positive or negative ion, allowing for a wide range of properties.
• D. Silicon can bond in a long two-dimensional form allowing it to be used as a coating for other metal alloys.

Answer 1

The correct option is C Silicon can be bonded to form either a positive or negative ion, allowing for a wide range of properties.

Doping means the introduction of impurities into a semiconductor crystal to the defined modification of conductivity.

Elements with 3 valence electrons are used for p-type doping, 5-valued elements for n-doping.
