The direct-gap transition peak (A peak) can be fitted with two peaks: A exciton peak and A− trion peak45, shown in the inserted figure in Fig. 7b. The A− trion peak is sensitive to the electron density and the intensity will decrease by p-doping46. The Ape−atkrisolinghint...

5,6. While the charge carrier mobilities in phosphorene are comparable to those in a ML of MoS2, being a single-element material, phosphorene can, at least potentially, be fabricated at higher purity. Fig. 1: Photoluminescence of phosphorene....
This electron-hole pair is called an exciton. Intrinsically, the electron is transferred to the LUMO (lowest unoccupied molecular orbital) and the hole to the HOMO (highest occupied molecular orbital). After a short time period, the exciton reunites and a photon with lower energy than the ...
It has been especially studied because of its appealing electronic properties, i.e., a wide band gap (3.7 eV) and a high exciton binding energy (40 meV). Zinc sulphide is among the most appealing semiconducting materials for the development of electroluminescent devices [46,301,387], which ...

To investigate the properties of a two-dimensional carrier gas at intermediate densities, we perform picosecond transient four-wave mixing experiments on trions (charged excitons) and neutral excitons in modulation p-doped CdTe/Cd1-x-yMgxZnyTe quantum wells. The determination of trion and exciton ...
