AC Response Across the Metal Insulator Transition of YBCO Josephson Junctions Fabricated with a Helium Ion Beam
Adhilsha Parachikunnumal, Nirjhar Sarkar, Aravind Rajeev Sreeja +5
Using focused helium ion beam (FHIB) irradiation, we fabricated in-plane, high-Tc YBCO Josephson junctions. By varying the dose of the irradiation, we tune the junction barriers fr…
Pinching and Probing of Polygonal Grain Boundaries
Nirjhar Sarkar, Prabhakar R. Bandaru, Robert C. Dynes
In this study, sub-angstrom spatial resolution is achieved in mapping and spectroscopy of atoms and bonds within polygonal grain boundaries (GBs) of graphite using Scanning Tunneli…
Characteristic nanoscale deformations on large area coherent graphite moiré
Nirjhar Sarkar, Prabhakar R. Bandaru, Robert C. Dynes
Highly oriented pyrolytic graphite (HoPG) may be the only known monatomic crystal with the ability to host naturally formed moire patterns on its cleaved surfaces, which are cohere…
Probing interlayer van der Waals strengths of two-dimensional surfaces and defects, through STM tip-induced elastic deformations
Nirjhar Sarkar, Prabhakar R. Bandaru, Robert C. Dynes
A methodology to test the interlayer bonding strength of two-dimensional (2D) surfaces and associated one (1D)- and two (2D)- dimensional surface defects using scanning tunneling m…
