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.

 

[Dr Transport]

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...?

Phonon

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...
