Data for "Rabi Splitting in Confined Semiconductors: MoSe₂ Monolayers vs. (Ga,In)As Quantum Wells"

Abstract

This dataset contains the experimental and theoretical data presented in the paper “Rabi Splitting in Confined Semiconductors: MoSe₂ Monolayers vs. (Ga,In)As Quantum Wells.” An ultrafast pump-probe setup was used to investigate Rabi splitting phenomena in MoSe₂ monolayers and (Ga,In)As quantum wells. All datasets are provided in tab-separated values format. Most files begin with a header row containing column titles that describe the respective contents and indicate the varied parameters. The main exception are the 2D datasets, where the first row lists the time delays in femtoseconds (fs) and the first column contains the photon energy in electronvolts (eV). Fig 1(a) experiment.txt This file contains experimentally measured absorption spectra of the MoSe₂ monolayer sample. The first column lists the energy in eV. The following columns show spectra recorded at different excitation fluences in μJ/cm², as well as the linear absorption of the sample and the spectrum of the excitation pulse. Fig 1(a) theory.txt This file contains theoretically computed absorption spectra of the MoSe₂ monolayer sample. The first column lists the energy in eV. The following columns show spectra recorded at different excitation fluences in μJ/cm², as well as the linear absorption of the sample and the spectrum of the excitation pulse. Fig 1(b) experiment.txt This file contains a 2D false-color dataset of the nonlinear absorption of the MoSe₂ monolayer. The first row lists time delays in femtoseconds, and the first column provides the energy in eV. The remaining columns represent absorption spectra as a function of time delay for an excitation energy density of 16 μJ/cm². Fig 1(b) theory.txt This file contains a 2D false-color simulated dataset of the nonlinear absorption of the MoSe₂ monolayer. The first row lists time delays in femtoseconds, and the first column provides the energy in eV. The remaining columns represent absorption spectra as a function of time delay for an excitation energy density of 16 μJ/cm². Fig 2(a) experiment.txt This file shows the measured time-resolved absorption of a (Ga,In)As multiple quantum well (MQW) sample. The first row contains time delays in fs; the first column contains the photon energy in eV. The remaining columns show the absorption spectra at different time points, excited at t = 0 fs. Fig 2(a) theory.txt This file shows the calculated time-resolved absorption of a (Ga,In)As MQW sample. The first row contains time delays in fs; the first column contains the photon energy in eV. The remaining columns show the calculated absorption spectra at different time points, excited at t = 0 fs. Fig 2(a) inset.txt This file contains additional data shown in the inset of Figure 2(a). The first column gives the energy in eV, the second column shows the linear absorption of the (Ga,In)As sample, and the third column contains the excitation pulse spectrum. Fig 2(b) experiment.txt This file contains measured transient absorption changes in the (Ga,In)As MQW sample under varying excitation fluences. The first column lists time in fs, and the following columns contain the transient absorption signals for increasing fluence values. Fig 2(b) theory.txt This file contains calculated transient absorption changes in the (Ga,In)As MQW sample under varying excitation fluences. This file has the same format as Fig 2(b) experiment.txt but includes theoretically calculated transients. Additionally, the temporal profile of the excitation pulse is included. Fig 3(a).txt This file contains absorption spectra of the (Ga,In)As sample for various excitation fluences. The first column shows the photon energy in eV. The subsequent columns contain the absorption spectra for different fluences, followed by the excitation pulse spectrum at the end. Fig 3(b) MoSe_2.txt This file shows the energy positions of the absorption peaks in the MoSe₂ monolayer sample as a function of the square root of the pump power. The first column lists √(pump power), and the second column contains the corresponding peak energies. Fig 3(b) MQW.txt This file presents the energy positions of the absorption peaks from the MQW spectra shown in Fig 3(a), plotted as a function of the square root of the pump power. The first column lists √(pump power), and the second column contains the corresponding peak energies. Fig 4(a) experiment.txt This file contains the changes in absorption spectra of the MoSe₂ sample recorded at different excitation fluences. The first column lists the photon energy in eV. The remaining columns contain the spectra for increasing fluence values. Fig 4(b) theory.txt This file mirrors the structure of Fig 4(a) experiment.txt but contains theoretical absorption spectra calculated for the same fluence conditions. Fig 7.txt This file provides data used to determine the absorption spectrum of the MoSe₂ sample. The first column lists the photon energy in eV, the second column shows the measured transmission, the third column contains a fitted curve excluding the absorption dip, and the fourth column gives the resulting calculated absorption.
