Question

1. Given the momentum discrete spacing in a channel as 2.18 ×10^-11 fm. Calculate the length of the channel assuming a 1-D conductor.          
2. If the momentum is given as 8×10^-24 kg-m/s, calculate the integer n, which is the multiple of the discrete spacing using the length you obtained in 2).    
3. Explain in your own words, the reason for momentum discretization for electrons moving inside a crystalline solid.                
   C2 E Question 2: The diagram below shows two particles with different energy verses momentum relationships, denoted by Cl and C2, respectively. 1) Determine the curve that exhibits a larger mass. Use your own words to explain your answer. 2) Explain in your own words, how the energy momentum relationship can be used to obtain the density of states D(E) diagram V C1 →P
