Harnessing the VO2 Phase Transition for Automatic Gain Control in Transimpedance Amplifiers
Amir Gildor, Sariel Hodisan, Shahar Kvatinsky +1
Transimpedance amplifiers (TIAs) are essential in sensor electronics, converting input currents into output voltages. Conventional TIAs utilize fixed-gain resistors, which saturate…
Disentangling pre-transitional fluctuations in metallic VO2
Javier del Valle, Carl Willem Rischau, Artem Korshunov +8
VO2 features concomitant structural and metal-insulator transitions. This poses a challenge for understanding the underlying mechanism: is the transition triggered by a structural…
Martensitic laminate geometry controls electronic phase transitions in a Mott insulator
Ziming Shao, Benjamin Gregory, Suchismita Sarker +4
Symmetry-lowering structural phase transitions result in multiple degenerate structures whose coexistence is determined by macroscopic strain compatibility. In quantum materials, t…
Reversal of strain state in a Mott insulator thin film by controlling substrate morphology
Reetendra Singh, Abhishek Rakshit, Galit Atiya +3
The V2O3 phase diagram contains two insulating phases and one metallic phase with different lattice structures. The stability of these phases is very sensitive to pressure, offerin…
Memory in strain-tuned insulator-metal-insulator sequence of transitions after photoexcitation in the Mott material V2O3
O. Yu. Gorobtsov, Y. Kalcheim, Z. Shao +9
Memory effects during metal-insulator transitions in quantum materials reveal complex physics and potential for novel electronics mimicking biological neural systems. Nonetheless,…
Magnetic precursor to the structural phase transition in VO
Chubin Huang, Abhishek Rakshit, Gianluca Janka +5
The coupling between structural, electronic and magnetic degrees of freedom across the metal-insulator transition in V2O3 makes it hard to determine the main driving mechanism behi…
