Sign reversal of magnetoresistance and p to n transition in Ni doped ZnO thin film
Arpana Agrawal, Tanveer A. Darb, R. J. Choudhary +3
We report the magnetoresistance and nonlinear Hall effect studies over a wide temperature range in pulsed laser deposited Ni0.07Zn0.93O thin film. Negative and positive contributio…
Temperature induced transition from p-n to n-n electronic behavior in Ni0.07Zn0.93O/Mg0.21Zn0.79O heterojunction
Tanveer A. Dar, Arpana Agrawal, Ram J. Choudhary +3
The transport characteristics across the pulsed laser deposited Ni0.07Zn0.93O/Mg0.21Zn0.79O heterojunction exhibits p-n type semiconducting properties at 10 K while at 100 K, its c…
Effect of shell thickness on exciton and biexciton binding energy of a ZnSe/ZnS core/shell quantum dot
Pratima Sen, Saikat Chattopadhyay, J. T. Andrews +1
The exciton and biexciton binding energy have been studied for a ZnSe/ZnS core/shell quantum dot using WKB (Wentzel-Kramers-Brillouin) approximation. The exciton binding energy inc…
Forces on a nanoparticle in an optical trap
Kaushik Choudhury, Joseph Thomas Andrews, Pranay Kumar Sen +1
Forces on a nanoparticle in an optical trap are analysed. Brownian motion is found to be one of the major challenges to trap a nanoparticle. Accordingly, suitable spatial electric…
