Growth mechanism of nanocrystals in solution: ZnO, a case study
Ranjani Viswanatha, Pralay K. Santra, Chandan Dasgupta +1
We investigate the mechanism of growth of nanocrystals from solution using the case of ZnO. Spanning a wide range of values of the parameters, such as the temperature and the react…
Electronic structure of and Quantum size effect in III-V and II-VI semiconducting nanocrystals using a realistic tight binding approach
Ranjani Viswanatha, Sameer Sapra, Tanusri Saha-Dasgupta +1
We analyze the electronic structure of group III-V semiconductors obtained within full potential linearized augmented plane wave (FP-LAPW) method and arrive at a realistic and mini…
An accurate description of quantum size effects in InP nanocrystallites over a wide range of sizes
Sameer Sapra, Ranjani Viswanatha, D. D. Sarma
We obtain an effective parametrization of the bulk electronic structure of InP within the Tight Binding scheme. Using these parameters, we calculate the electronic structure of InP…
