SUMMARY

The discussion focuses on key concepts related to solving 2D Density of States (DOS) problems in physics. It outlines the formulas for the density of k-states g(k) = L²*k/2*π, the density of states g(E) = L²*m/π*h², and the density of states per area n2D(E) = m*/π*h². Additionally, it emphasizes the importance of graphing n2D(E) versus energy E and calculating n2D(E) as a quantitative measure. The post seeks guidance on these concepts and encourages further exploration of the topic.

Homework Statement


(a) the density of k-states g(k) = L^2*k/2*Pi.
(b) the density of states g(E) = L^2*m/Pi*h^2
(c)The density of states per area n2D(E)=m*/Pi*h^2
(d) Sketch a graph of n2D(E) vs E.
(e) Calculate n2D(E) as a quantity.

The questions don't have to be answered in full a general description and pointing me the right direction itself would be a huge help. Cheers. As this is my first time posting I am not sure of what else to include with the post.
