This research advances quantum materials characterization by introducing an efficient analytical method to extract quasiparticle bandgaps and screening lengths from exciton spectra in 2D semiconductors. By utilizing a modified Kratzer model, the approach eliminates computationally intensive numerical fitting while accurately predicting magnetoexciton properties for various transition-metal dichalcogenides. This streamlined framework offers significant practical value for researchers developing next-generation quantum devices who require precise material parameters without heavy computational overhead.
Exciton Spectra & Quantum Bandgaps, Screening Via Analytical Inversion
Analyze monolayer materials: this work retrieves the quasiparticle bandgap & screening length from optical exciton spectra, using the first three excitonic states.
Researchers have developed a method to determine key material properties of two-dimensional semiconductors by analyzing exciton spectra. Duy-Nhat Ly, Thanh-Son Nguyen, Ngoc-Tram D. Hoang, and Van-Hoang Le of Ho Chi Minh City University of Education created an analytical procedure based on a solvable modified Kratzer model to retrieve parameters from monolayer transition-metal dichalcogenides. The work determines quasiparticle bandgaps, effective screening parameters, and energy scaling factors directly from the experimentally measured energies of the three lowest excitonic…
