Optical and Terahertz Response of Carbon Nanostructures
Arvind Singh, Sunil Kumar
In the last three decades or so, we have witnessed an extraordinary progress in the research and technology of carbon-based nanomaterials. Among the peculiar highlights are the dis…
Optical Damage Threshold and THz Generation Efficiency of (Fe,CoFeB)/(Ta,Pt) Spintronic Emitters
Sandeep Kumar, Anand Nivedan, Arvind Singh +5
THz pulses are generated from femtosecond pulse-excited ferromagnetic/nonmagnetic spintronic heterostructures via inverse spin Hall effect. The contribution from ultrafast demagnet…
THz pulses from optically excited Fe, Pt and Ta based Spintronic Heterostructures
Sandeep Kumar, Anand Nivedan, Arvind Singh +1
Spintronic heterostructures are considered to be the new generation THz sources for their capability in producing high power and broadband THz radiation. Here, we provide a brief r…
Enhancement in optically induced ultrafast THz response of MoSe2MoS2 heterobilayer
Sunil Kumar, Arvind Singh, Sandeep Kumar +7
THz conductivity of large area MoS2 and MoSe2 monolayers as well as their vertical heterostructure, MoSe2MoS2 is measured in the 0.3-5 THz frequency range. Compared to the monolaye…
