Question

The Fermi energy of a material is 3.45 eV. What is the zero-point energy of the material?

(a) 1.02 eV

(b) 2.07 eV

(c) 3.45 eV

(d) 4.16 eV

Answer 1

Correct option is (b) 2.07 eV

To elaborate: As we know, the fermi energy of the material is 3.45 eV.

Now, zero-point energy =(frac{3}{5}E_F)

= 3/5 X 3.45 eV

= 2.07 eV.
