Option 2 is true about semiconductors. You can change how easily electrons move through them.
What are semiconductors?
Semiconductors are materials with conductivity intermediate between conductors and nonconductors or insulators. Semiconductors may be either compound like gallium arsenide.
The ideas, characteristics, and mathematical techniques that control semiconductors are explained in physics.
When the semiconductors become charged, current flows from the negative one to the positive one. Current flow in a semiconductor is caused by charge carrier migration in both the conduction and valence bands.
In a semiconductor, you can change how easily electrons move through them.
