Pairs of Gold Electrodes with Nanometer Separation Performed over SiO Substrates with a Molecular Adhesion Monolayer
Ajit K. Mahapatro, Subhasis Ghosh, David B. Janes
Pairs of electrodes with nanometer separation (nano-gap) are achieved through an electromigration-induced break-junction (EIBJ) technique at room temperature. Lithographically defi…
The Origin of Stokes Shift in Semiconductor Quantum Dots
Anjana Bagga, P. K. Chattopadhyay, Subhasis Ghosh
The mechanism of Stokes shift in semiconductor quantum dots is investigated by calculating the energy of the excitonic states. We have taken into account all possible contributions…
Energy Levels in Spheroidal Quantum Dot
Anjana Bagga, P. K. Chattopadhyay, Subhasis Ghosh
The effect of non-sphericity of the quantum dot on the eigenvalues and eigenfunctions has been investigated for the case of both the finite and infinite barrier. The ground and exc…
Photoluminescence Spectroscopy of many-body Effects in Heavily Doped AlGaAs
Subhasis Ghosh, Niladri Sarkar
We present an experimental investigation of heavy doping-induced many-body effects such as band gap narrowing(BGN) and Fermi edge singularity(FES) in AlGaAs using photo…
