Carrier Dynamics in High-density Photo-doped MoS: Monolayer vs Multilayer
Durga Prasad Khatua, Asha Singh, Sabina Gurung +1
Monolayer and multilayer MoS are extremely fascinating materials for the use in lasers, compact optical parametric amplifiers, and high-power detectors which demands high excit…
Ultrafast Carrier Dynamics in Ag-CdTe Hybrid Nanostructure: Non-radiative and Radiative Relaxations
Sabina Gurung, Durga Prasad Khatua, Asha Singh +1
In this article, we study non-radiative and radiative relaxation processes in a hybrid formed by combining Ag nanoparticle (NP) and CdTe quantum dots (QD) using transient transmiss…
Filtering Noise in Time and Frequency Domain for Ultrafast Pump-Probe Performed Using Low Repetition Rate Lasers
Durga Prasad Khatua, Sabina Gurung, Asha Singh +3
Optical pump-probe spectroscopy is a powerful tool to directly probe the carrier dynamics in materials down to sub-femtosecond resolution. To perform such measurement, while keepin…
Role of Auger Recombination in Plasmon Controlled Photoluminescence Kinetics in Metal-Semiconductor Hybrid Nanostructures
Sabina Gurung, Asha Singh, J. Jayabalan
Spectroscopic studies of semiconductor quantum dots (SQDs) addressing the problem of non-radiative carrier losses is vital for the improvement in the efficiency of various light-em…
Static and Ultrafast Optical Response of Two Ag Nanospheres Glued by a CdTe Quantum Dot
Sabina Gurung, Asha Singh, Durga Prasad Khatua +2
A hot-spot of high local field can be created in between two closely placed metal nanoparticles by irradiating them with an appropriate wavelength and polarization of incident ligh…
