Semiconductors

Question 1

Conductor

Answer 1

• Allow electrons to flow freely due to their atomic structure
• Example: gold, copper.
• low resistance to electrical current

Question 2

Insulator

Answer 2

• Materials that resist the flow of electrons because electrons are tightly bound to their atoms
• High-resistance; little to no current can flow through them

Question 3

Semi-conductors

Answer 3

• Conduct electrons under increased energy conditions
• Example: applying heat to silicon

Question 4

Transistors

Answer 4

• Semiconductor device used to amplify or switch electrical signals and power
• Apply voltage to the gate to control the flow from the source to the drain - On/Off
• Wiring multiple transistors enables the AND, OR, NOT logic

Question 5

Bipolar Junction Transistors

Answer 5

• Three layers of semiconductor materials
• Arranged an NPN or PNP
• Emitter
• Base
• Collector
• Analog circuits
• Current driven

Question 5

Field Effect Transistors

Answer 5

• Three layers of semiconductor materials
• Arranged an NPN or PNP
• Digital Circuits
• Voltage driven
