calculate the density of states and average energy for an elctron gas in 1d,2d and 3d(adsbygoogle = window.adsbygoogle || []).push({});

I know the number of states is

[tex]

N= \int_{0}^{infinity} g(e)f(e) de

[/tex]

[tex]

and E = \int_{0}^{infinity} g(e)ef(e) de

[/tex]

[tex]

and g(e) =dN/de

[/tex]
