Phys. Rev. B 69, 125304 (2004) [7 pages]Evolution of the electronic structure with size in II-VI semiconductor nanocrystals
Sameer Sapra and D. D. Sarma * Received 17 July 2003; published 8 March 2004 In order to provide a quantitatively accurate description of the band-gap variation with sizes in various II-VI semiconductor nanocrystals, we make use of the recently reported tight-binding parametrization of the corresponding bulk systems. Using the same tight-binding scheme and parameters, we calculate the electronic structure of II-VI nanocrystals in real space with sizes ranging between 5 and 80 Å in diameter. A comparison with available experimental results from the literature shows an excellent agreement over the entire range of sizes. ©2004 The American Physical Society
