Enhancing the ultrafast third order nonlinear optical response by charge transfer in VSe2-reduced graphene oxide hybrid
Vinod Kumar, Afreen, K. A. Sree Raj +4
Nonlinear optical phenomena play a critical role in understanding microscopic light-matter interactions and have far-reaching applications across various fields, such as biosensing…
Room temperature electron-hole liquid phase in monolayer MoSiZ (Z = pinctogen)
Pushpendra Yadav, K. V. Adarsh, Amit Agarwal
Photo-excited electrons and holes in insulators, above a critical density and below a critical temperature, can condense to form an electron-hole liquid (EHL) phase. However, obser…
Strongly bound excitons in monolayer MoSiZ (Z = pnictogen)
Pushpendra Yadav, Bramhachari Khamari, Bahadur Singh +2
Reduced dielectric screening in two-dimensional materials enables bound excitons, which modifies their optical absorption and optoelectronic response even at room temperature. Here…
Nonlinear Optical Limiting with Hybrid Nanostructures of NiCo2O4 and Multiwall Carbon Nanotubes
Ankit Sharma, Pritam Khan, Mansi Pathak +2
Nonlinear optical (NLO) response in terms of reverse saturable absorption (RSA) has been exploited extensively for optical limiting. Here, we experimentally demonstrate that flower…
Unveiling and engineering of third order optical nonlinearities in NiCoO nanoflowers
Ankit Sharma, Pritam Khan, Dipendranath Mandal +3
In this paper, we demonstrate NiCoO (NCO) as an efficient new nonlinear optical material with straightforward potential applications in optical limiting devices. We obtain…
Kinetics of photo-dissolution within Ag/As2S3 heterostructure
Pritam Khan, Yinsheng Xu, William Leon +4
Chalcogenide glass-silver heterostructures are candidates for photoresist and diffractive optical applications. To optimize their processing, we report the kinetics of Ag photo-dis…
Ultrafast light-induced softening of chalcogenide thin films above the rigidity percolation transition
Pritam Khan, Rajesh Kumar Yadav, K. V. Adarsh
Little is known about the role of network rigidity in light-induced structural rearrangements in network glasses due to a lack of supporting experiments and theories. In this repor…
Role of Ge:As ratio in controlling the light-induced response of a-GexAs35-xSe65 thin films
Pritam Khan, H. Jain, K. V. Adarsh
In this paper, we present interesting results on the quantification of photodarkening (PD), photobleaching (PB) and transient PD (TPD) in a- GexAs35-xSe65 thin films as a function…
