Interplay of filling fraction and coherence in symmetry broken graphene p-n junction
Arup Kumar Paul, Manas Ranjan Sahu, Chandan Kumar +3
The coherence of quantum Hall (QH) edges play the deciding factor in demonstrating an electron interferometer, which has potential to realize a topological qubit. A Graphene p-n ju…
Equilibration of Quantum hall edges in symmetry broken bilayer graphene
Chandan Kumar, Saurabh Kumar Srivastav, Anindya Das
Equilibration of quantum Hall edges is studied in a high quality dual gated bilayer graphene device in both unipolar and bipolar regime when all the degeneracies of the zero energy…
Equilibration of quantum hall edge states and its conductance fluctuations in graphene p-n junctions
Chandan Kumar, Manabendra Kuiri, Anindya Das
We report an observation of conductance fuctuations (CFs) in the bipolar regime of quantum hall (QH) plateaus in graphene (p-n-p/n-p-n) devices. The CFs in the bipolar regime are s…
Electron-Hole Asymmetry in the Electron-phonon Coupling in Top-gated Phosphorene Transistor
Biswanath Chakraborty, Satyendra Nath Gupta, Anjali Singh +6
Using in-situ Raman scattering from phosphorene channel in an electrochemically top-gated field effect transistor, we show that its phonons with A symmetry depend much more str…
