In semiconductors, photo-excited charge carriers exist as a gas of electrons and holes, bound electron–hole pairs (excitons), biexcitons and trions1–4. At sufficiently high densities, the non-equilibrium system of electrons (e−) and holes (h+)

We present results of polarization-resolved differential transmission experiments, in which pump and probe pulses are quasi-resonant with charged and neutral excitons in monolayer WSe 2 . By selecting co- and cross-circular polarization configuration

We investigate valley polarization dynamics of trions in WSe 2 in resonant pump-probe experiments. Intra- and inter-valley trions show distinct polarization dynamics, the former exhibits long-lived valley polarization (> 25 ps), the latter a fast dec

We investigate valley dynamics associated with trions in monolayer tungsten diselenide (WSe_{2}) using polarization resolved two-color pump-probe spectroscopy. When tuning the pump and probe energy across the trion resonance, distinct trion valley po

We report charged exciton (trion) formation dynamics in doped monolayer transition metal dichalcogenides (TMDs), specifically molybdenum diselenide (MoSe2), using resonant two-color pump-probe spectroscopy. When resonantly pumping the exciton transit

The utilization of fluorescence quenching microscopy (FQM) for quick visualization of chemical functionalization in relatively large regions of graphene, grown via chemical vapor deposition (CVD), is discussed. Through reactive ion plasma etching, pa

Fluorescence Quenching Microscopy has been shown to be an effective means of characterizing graphene on the macroscale. Centimeter-scale CVD-grown pristine and doped graphene were manufactured in a high temperature (1000°C) furnace on pristine coppe
