Atomistic study of finite temperature properties in ferroelectric BiAlO
Indranil Mal, Chandan Kumar Vishwakarma, Mohd Zeeshan +2
The lead-free perovskite ferroelectrics captivate researchers with their unique functional properties leading to important technological applications. In the search for a new lead-…
Charge dynamics at nitrogen impurities and nitrogen-vacancy centers in diamond
Chandan Kumar Vishwakarma, J. K. Nangoi, Mark E. Turiansky +1
The nitrogen-vacancy (NV) center in diamond is the prototype quantum defect that enables a variety of diamond-based quantum technologies. However, charge-state instability and spec…
Some new results on permutation trinomials over finite fields with even characteristic
Kirpa Garg, Sartaj Ul Hasan, Chandan Kumar Vishwakarma
The construction of permutation trinomials of the form over $\F_{2^{2m}}$, where are positive integers, is an active…
Emergence of half-metallic ferromagnetism and valley polarization in transition metal substituted WSTe monolayer
Shivani Kumawat, Chandan Kumar Vishwakarma, Mohd Zeeshan +3
Two-dimensional (2D) Janus materials hold a great importance in spintronic and valleytronic applications due to their unique lattice structures and emergent properties. They intrin…
