Assignee: RENSSELAER POLYTECHNIC INSTITUTE
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 8:
9. A system for revealing excitons in a transition metal dichalcogenides comprising:
a broadband light source configured to emit excitation photon energy;
a tunable filter configured to filter to excitation photon energy to a predetermined wavelength bandwidth;
a linear polarizer configured to linearly polarize the filtered excitation photon energy;
a quarter waveplate configured to convert the linearly polarized excitation photon energy into circularly polarized excitation photon energy; and
a focusing element configured to focus the circularly polarized excitation photon energy to excite the transition metal dichalcogenides positioned on a piezo stage microscope;
wherein an external magnetic field is applied to the transition metal dichalcogenides when it is exposed to the focused circularly polarized excitation photon energy.
