Calculating the DOS for spherical quantum dot

[skgupta-phy]

Dears

Is any method to calculate the density of states of spherical (purely) quantum dot?

Well since a quantum dot is just a cluster of atoms yes, you can calculate it's DOS using DFT.

The DOS for a quantum dot is a series of delta functions, the derivation can be found in Koch's text

What DOS do you want to calculate, phonon, electron...?

PHONONS, I WANT TO CALCULATE PHONONS VIA THIE , BASICALLY INTERESTED WITH ACOUSTIC PHONONS.

thanks, but i want to know how exactly...basically i am using quantum ezpresso 3.1.1 for DFT.
so please guide me...
