Excited-state dynamics of structurally characterized crystal of SnxSb1-x
Prince Sharma, M. M. Sharma, Kapil Kumar +2
The topological behavior of heavy metal alloys opens a vast area for incredible research and future technology. Here, we extend our previous report about the superconducting proper…
Metal Doping in Topological Insulators- A Key for Tunable Generation of Terahertz
Prince Sharma1, M. M Sharma, Mahesh Kumar +1
The unique surface edge states make topological insulators a primary focus among different applications. In this article, we synthesized a large single crystal of Niobium(Nb)-doped…
Exploration of terahertz from time-resolved ultrafast spectroscopy in single-crystal Bi2Se3 topological insulator
Prince Sharma, Mahesh Kumar, V. P. S. Awana
In this article, we reconnoiter the differential reflection signal of a Bi2Se3 single crystal flake, using ultrafast transient absorption spectroscopy in the femtosecond time domai…
Anisotropic Electron-Photon-Phonon Coupling in Layered MoS2
Deepu Kumar, Birender Singh, Rahul Kumar +2
Transition metal dichalcogenide, especially MoS2 has attracted lot of attention recently owing to its tunable visible range band gap and anisotropic electronic and transport proper…
