Optical Kerr nonlinearity and multi-photon absorption of DSTMS measured by Z-scan method
Jiang Li, Rakesh Rana, Liguo Zhu +3
We investigate the optical Kerr nonlinearity and multi-photon absorption (MPA) properties of DSTMS excited by femtosecond pulses at a wavelengths of 1.43 μm, which is optimal for t…
Nonlinear Charge Transport in InGaAs Nanowires at Terahertz Frequencies
Rakesh Rana, Leila Balaghi, Ivan Fotev +4
We probe the electron transport properties in the shell of GaAs/In0.2Ga0.8As core/shell nanowires at high electric fields using optical pump / THz probe spectroscopy with broadband…
Non-thermal nature of photo-induced insulator-to-metal transition in NbO
Rakesh Rana, J. Michael Klopf, Jörg Grenzer +3
We study the photo-induced metallization process in niobium dioxide NbO. This compound undergoes the thermal insulator-to-metal transition at the remarkably high temperature of…
Carrier driven antiferromagnetism and exchange-bias in SrRuO3/CaRuO3 heterostructures
Parul Pandey, Ching-Hao Chang, Angus Huang +7
Oxide heterostructures exhibit a rich variety of magnetic and transport properties which arise due to contact at an interface. This can lead to surprising effects that are very dif…
Observation and Structural Control of Charge-Density-Waves resonating with Terahertz Frequencies in NdNiO3
Rakesh Rana, Parul Pandey, S. S. Prabhu +1
Formation of charge-density-waves in ordered electronic phases (such as charge-order) is an emergent phenomenon in the perovskite class of correlated oxides. This scenario is visua…
Ferromagnetism in CaRuO3 thin films by efficient route of tensile epitaxial strain
Shivendra Tripathi, Rakesh Rana, Parul Pandey +2
We show that a ferromagnetic (FM) order in the orthorhombic CaRuO3, which is a non-magnetic and iso-structural analog of FM system SrRuO3, can be established and stabilized by the…
