areas of expertise

Research Experience:

  • Conducted experimental research at Miami University-Physics department in the field of condensed matter physics, specifically novel magnetic materials:

     

    1. Synthesis alloys using an arc melting technique, followed by high-temperature annealing, sintering and quenching. 

       

    2. Investigated magnetic and structural transitions, and exchange bias effect through x-ray diffraction, magnetization, and susceptibility, primarily using the Quantum Design Physical Property Measurement System.

 

  • Conducted experimental research at University of South Florida-Physics department in the field of condensed matter physics, specifically the photophysics of low dimensional, solution processable semiconductors:

     

    1. Synthesis of hybrid organic-inorganic halide perovskites (HOIP) solar cell using spin-coating and spray-coating techniques.

       

    2. Synthesis of semiconductor 2D materials Transition Metal Dichalcogenides (TMDs) via Chemical Vapor Deposition (CVD).

 

 

  1. Optical characterization using Raman spectroscopy and photoluminescence.

     

    1. Structural characterization using X-ray diffraction and atomic force microscopy (AFM).

 

  1. Morphological characterization using scanning electron microscopy (SEM) and optical microscopy.

 

  1. Research expertise of more than 3+ years in optics, involving super resolution nano-imaging using tip enhanced photoluminescence (TEPL) and tip enhanced Raman spectroscopy (TERS) of 2D Transition metal dichalcogenides (TMDs). Analysis of these materials is carried out in both classical and quantum regime (quantum plasmonics).

 

  1. During my PhD, we successfully achieved generation and nanoscale optical characterization of nanobubbles in 2D materials and lateral heterostructures using nanoindentation control of the bubble morphology. We showed the first demonstration of TEPL measurements of freestanding 2D materials and nanoribbons (unique 1D-on-2D structures). We also introduce two new novel nanoscale imaging techniques based on the reduction of the PL and Raman signals by the mechanical nanoindentation influence of the tip.
