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…
Sub-bandgap activated charges transfer in a graphene-MoS2-graphene heterostructure
Sunil Kumar, Arvind Singh, Anand Nivedan +7
Monolayers of transition metal dichalcogenides are semiconducting materials which offer many prospects in optoelectronics. A monolayer of molybdenum disulfide (MoS2) has a direct b…
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…
Study of the photo-switching of a Fe(II) chiral complex through linear and nonlinear ultrafast spectroscopy
Amine Hamouda, Fredéric Dutin, Jerome Degert +4
Photo-switching the physical properties of molecular systems opens large possibilities for driving materials far from equilibrium toward new states. Moreover, ultra-short pulses of…
Tuning Photoinduced Terahertz Conductivity in Monolayer Graphene: Optical Pump Terahertz Probe Spectroscopy
Srabani Kar, Dipti R. Mohapatra, Eric Freysz +1
Optical pump-terahertz probe differential transmission measurements of as-prepared single layer graphene (AG)(unintentionally hole doped with Fermi energy at 180 meV),…
