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…
Evolution of the electronic structure with size in II-VI semiconductor nanocrystals
Sameer Sapra, D. D. Sarma
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 tig…
Realistic Tight Binding Model for the Electronic Structure of II-VI Semiconductors
Sameer Sapra, N. Shanthi, D. D. Sarma
We analyze the electronic structure of group II-VI semiconductors obtained within LMTO approach in order to arrive at a realistic and minimal tight binding model, parameterized to…
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…
