THz Photodetector using sideband-modulated transport through surface states of a 3D Topological Insulator
Puja Mondal, Sankalpa Ghosh, Manish Sharma
The transport properties of the surface charge carriers of a three dimensional topological insulator under a terahertz (THz) field along with a resonant double barrier structure is…
Scattering of massless Dirac fermions in circular p-n junctions with and without magnetic field
Neetu Agrawal, Sankalpa Ghosh, Manish Sharma
In the absence of a magnetic field, scattered wavefunction inside a circular p-n junction in graphene exhibits an interference pattern with high intensity maximum located around th…
Electron optics with dirac fermions: electron transport in monolayer and bilayer graphene through magnetic barrier and their superlattices
Neetu Agrawal, Sankalpa Ghosh, Manish Sharma
In this review article we discuss the recent progress in studying ballistic transport for charge carriers in graphene through highly inhomogenous magnetic field known as magnetic b…
Dynamics of magnetic nanoparticle suspensions
Vanchna Singh, Varsha Banerjee, Manish Sharma
We study the dynamics of a suspension of magnetic nanoparticles. Their relaxation times are strongly size-dependent. The dominant mode of relaxation is also governed by the size of…
A Green's function approach to transmission of massless Dirac fermions in graphene through an array of random scatterers
Neetu Agrawal, Sankalpa Ghosh, Manish Sharma
We consider the transmission of massless Dirac fermions through an array of short range scatterers which are modeled as randomly positioned - function like potentials along the…
A Transfer Matrix Approach to Electron Transport in Graphene through Arbitrary Electric and Magnetic Potential Barriers
Sameer Grover, Sankalpa Ghosh, Manish Sharma
A transfer matrix method is presented for solving the scattering problem for the quasi one-dimensional massless Dirac equation applied to graphene in the presence of an arbitrary i…
