Core-Shell to Doped Quantum Dots: Evolution of the Local Environment Using XAFS

Saha, Avijit; Chattopadhyay, Soma; Shibata, Tomohiro; Viswanatha, Ranjani (American Chemical Society, 2016)

Internal structure study at an atomic level is a challenging task with far reaching consequences to its material properties, specifically in the field of transition metal doping in quantum dots. Diffusion of transition ...
The curious case of CdTe/CdS: photoabsorption versus photoemission

Saha, Avijit; Chattopadhyay, Soma; Shibata, Tomohiro; Viswanatha, Ranjani (Royal Society of Chemistry, 2014)

The potential of nanomaterials arises from the fine tuning of material properties by changing their composition, size and shape. Here, we show that by varying the local Cd and Te/S environment using CdTe/CdS as the host, ...
Uniform Doping in Quantum-Dots-Based Dilute Magnetic Semiconductor

Saha, Avijit; Shetty, Amitha; Pavan, A. R.; Chattopadhyay, Soma; Shibata, Tomohiro; Viswanatha, Ranjani (American Chemical Society, 2016)

Effective manipulation of magnetic spin within a semiconductor leading to a search for ferromagnets with semiconducting properties has evolved into an important field of dilute magnetic semiconductors (DMS). Although a lot ...
