Answer 1

An intrinsic semiconductor is neither a good conductor not a good insulator. ------> TRUE

Semiconductors are materials that have medium bandgap energies in the range of 1.1(eV) ----> TRUE

A covalent bond is formed when atoms lose valence shell electrons. ------> FALSE

Covalent bonding occurs when pairs of electronsare shared by atoms. Atoms will covalently bondwith other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

The n-type semiconductor material is formed by doingd Material with electron hours -----> FALSE

When an acceptor atom replaces a silicon atom in the crystal, a vacant state (an electron "hole") is created, which can move around the lattice and functions as a charge carrier. Therefore, a silicon crystal doped with boron creates a p-type semiconductor.

The ideal model of a diode is a switch. ----> TRUE
