Near-direct bandgap / type-II pn heterojunction for enhanced ultrafast photodetection and high-performance photovoltaics
Abin Varghese, Dipankar Saha, Kartikey Thakar +5
PN heterojunctions comprising layered van der Waals (vdW) semiconductors have been used to demonstrate current rectifiers, photodetectors, and photovoltaic devices. However, a dire…
The Avian Compass can be Sensitive even without Sustained Quantum Coherence
Rakshit Jain, Vishvendra Singh Poonia, Kasturi Saha +2
Theoretical studies indicating the presence of long-lived coherence in the radical pair system have engendered questions about the utilitarian role of sustained coherence in the av…
Effect of Tensile Strain in GaN Layer on the Band Offsets and 2DEG Density in AlGaN/GaN Heterostructures
Mihir Date, Sudipta Mukherjee, Joydeep Ghosh +3
We have addressed the existing ambiguity regarding the effect of process-induced strain in the underlying GaN layer on AlGaN/GaN heterostructure properties. The bandgaps and offset…
Quantum Biomimetic Modeling of Diamond NV Center Spin Dynamics
Vishvendra Singh Poonia, Dipankar Saha, Swaroop Ganguly
The spin dynamics of the diamond NV center turns out to be similar to that of the chemical compass responsible for avian magnetoreception. We present a simulation framework b…
On the functional window of the avian compass
Vishvendra Singh Poonia, Kiran Kondabagil, Dipankar Saha +1
The functional window is an experimentally observed property of the avian compass that refers to its selectivity around the geomagnetic field strength. We show that the radical-pai…
Fringe field control of one-dimensional room temperature quantum transport in site controlled AlGaN/GaN lateral nanowires
K. S. Akhil, Dolar Khachariya, Mudassar Meer +2
We have demonstrated effective fringe field control of one-dimensional electron gas (1-DEG) in AlGaN/GaN lateral nanowires. The nanowires are site controlled and formed by a combin…
