Answer:
a) Fermi level = 600 electron-volts
b)
Explanation:
Given data:
length of one-dimensional crystal = 10 um
Lattice spacing = 0.1 nm
A) Determine the Fermi level assuming one electron per atom
Total length = 10 <em>u</em>m
Interatomic separation of a = 0.1 nm
in this case the Atom has one electron therefore the number of electrons = 10^5 and the number of states Ns = gsN = 2 * 10^5 ( attached below is some part of the solution )
hence : Fermi level = 600 electron-volts
B) Determine the density of states as a function of electron energy
attached below is the detailed solution
Answer:
1)true
2)false
3)true
4)true
5)false,cz amatter is made of atoms while light is an electromagnetic radiation.
Kinetic energy-flashlight, and guitar
potential-coal,and composed spring
Can you input a picture??
1. becuase it is so hot that it could tan or be used to keep warm.
