Strain-Engineered Colloidal Quantum Dots for Nonclassical Light Emission

Parna Roy, Tanmay R Lodhi, A Daniel Praveen Kumar, Kartick Biswas et autres

Photonic quantum information processing stands to benefit from the realization of scalable, customizable emitters. While colloidally synthesized quantum dots address the challenge of scalability, better control over their properties remains desirable before the customizability challenge is fully addressed. To this end, better …

Interfacial and Bulk Switching MoS 2 Memristors for an All-2D Reservoir Computing Framework

Asmita S. Thool, Sourodeep Roy, Prahalad Kanti Barman, Kartick Biswas et autres

In this study, we report non-filamentary resistance switching with short- and long-term memory dynamics in Au/Ti/MoS 2 /Au memristive devices. The temporal dynamics is engineered by controlling the thickness of the chemical-vapor-deposited (CVD) MoS 2 films. Monolayer (1L)-MoS 2 devices exhibit forming-free …
