Semiconductor diodes

These are the characteristics of Trivalent impurities except

• •3 valence electrons

• •produce p-type semiconductors

• •producing a "hole".

• Antimony, arsenic, and phosphorus are the examples

The process of adding an impurity to an intrinsic semiconductor is called

• Doping

• Ionization

• Recombination

• Atomic modification

NGSS.HS-ETS1-3

Which among these is NOT the property of a semiconductor?

• Four electrons in the valence band forming covalent bonds

• At 0 Kelvin semiconductor acts like an insulator

• Semiconductors have two type of charge carriers

• Semiconductors are temperature insensitive

Diode 

•  allows current to flow in one direction
•  allows current to flow in two directions
• is a resistor

which statement is correct? (the dark circles represent the electrons)

• p-type of the diode is connected to the negative terminal.

• Electron moves across the p-n junction, makes the diode forward biased

• current will not flow in the circuit

• reverse biased circuit
