Size-Dependent Band-Tail Localization in Oxide Semiconductors Revealed by Direct Density-of-States Mapping
Chang Niu, Kisoo Nam, Aravindh Shankar +5
Disorder-induced localization is expected to become increasingly important as amorphous oxide semiconductor transistors are scaled toward low-dimensional channels, yet the electron…

Exploiting Negative Capacitance for Unconventional Coulomb Engineering
Aravindh Shankar, Pramey Upadhyaya, Supriyo Datta
The many-body ground state of a two-dimensional electron system can be tuned by Coulomb engineering through control of the dielectric environment. However, in conventional dielectr…

Sub-Terahertz Spin Relaxation Dynamics of Boron-Vacancy Centers in Hexagonal Boron Nitride
Abhishek Bharatbhai Solanki, Yueh-Chun Wu, Hamza Ather +12
Quantum sensors based on spin-defect relaxation have become powerful tools for detecting faint magnetic signals, yet their operation has remained largely confined to low magnetic f…
