Coulomb drag to thermopower response in dimensionally mismatched InAs nanowire-Graphene heterostructures and anisotropic noise in ReS2
Coulomb drag technique is a notable tool for probing electron-electron interaction in double-layer systems, where the momentum and energy transfer from one layer to the other layer as a result of Coulomb interaction. In ... -
Detection of charge-neutral modes to spin-wave excitations in graphene quantum Hall, and periodic magnetic field effect on Dirac electrons
In the quantum Hall (QH) regime, the electrical transport happens along the downstream chiral edge modes (dictated by the external magnetic field) while the bulk remains a vanilla insulator. However, it has been theoretically ... -
Exploring carrier dynamics in van-der-Waals heterostructures with shot noise spectroscopy, thermoelectricity and opto-electronic study
In the last two decades, there has been tremendous progress in two-dimensional (2D) - material research. It is mainly due to the availability of a large selection of 2D-materials and their van-der-Waals heterostructures. ... -
Quantized heat flow probing thermal equilibration and edge structures of quantum Hall phases in graphene
In condensed matter physics, usually, phases are described using Landau’s approach, which characterizes the phases in terms of underlying symmetries that are spontaneously broken. Over the past few decades, a different ... -
Quantum capacitance and noise measurements in van der Waals heterostructures
The discovery of graphene has revolutionized the field of condensed matter physics and opened new prospects for a wide range of other two-dimensional materials. Further with the advancement of fabrication techniques, one ... -
Quantum transport in Graphene Moire Superlattice and p-n junction
The discovery of graphene has revolutionized the field of mesoscopic condensed matter physics. It has started a new field of van-der Waals heterostructure in which different two-dimensional materials including graphene can ... -
Tuning Andreev reflection at Graphene - superconductor junction: from zero field to quantum Hall regime
Andreev reflection (AR) is the underlying phenomena that determines the quasiparticle dynamics at the junction of a superconductor with any non-superconducting material, which in turn determines the transport properties ...
