Monolayer transition metal dichalcogenide semiconductors host strongly bound two-dimensional excitonic complexes, and form an excellent platform for probing many-body physics through manipulation of Coulomb interaction. Quantum confined Stark effect is one of the routes to dynamically tune the emission line of these excitonic complexes. In this work, using a high quality graphene/hBN/WS$_2$/hBN/Au vertical heterojunction, we demonstrate for the first time, an out-of-plane electric field driven…

Highly tunable layered exciton in bilayer WS$_2$: linear quantum confined Stark effect versus electrostatic doping
In 1H monolayer transition metal dichalcogenide, the inversion symmetry is broken, while the reflection symmetry is maintained. On the contrary, in the bilayer, the inversion symmetry is restored,


Quantum-Confined Stark Effect of Individual Defects in a van der Waals Heterostructure.
By carefully designing sequences of metallic, insulating, and semiconducting two-dimensional materials, a van der Waals heterostructure field effect device with WSe2 hosting quantum emitters that is responsive to external static electric field applied to the device is fabricated.
Charge-tuneable biexciton complexes in monolayer WSe2
Experimental evidence of four- and five-particle biexciton complexes in monolayer WSe2 and their electrical control are reported and offer direct routes towards deterministic control in many-body quantum phenomena.
Dissociation of two-dimensional excitons in monolayer WSe2
This study investigates the main exciton dissociation pathway in p-n junctions of monolayer WSe2 by means of time and spectrally resolved photocurrent measurements and finds that under static in-plane electric field, excitons dissociate at a rate corresponding to the one predicted for tunnel ionization of 2D Wannier–Mott exciton.
Quantum-Confined Stark Effect in a MoS2 Monolayer van der Waals Heterostructure.
The photoluminescence emission energies of the neutral and charged excitons shift quadratically with the applied electric field, provided that the electron density remains constant, demonstrating that the exciton can be polarized.
Electrical Tuning of Interlayer Exciton Gases in WSe2 Bilayers.
Highly tunable interlayer excitons by an out-of-plane electric field in homobilayers of transition metal dichalcogenides are demonstrated and paved the way for the realization of degenerate exciton gases in atomically thin semiconductors.
Exciton Polarization and Renormalization Effect for Optical Modulation in Monolayer Semiconductors.
An electrolyte-gating method for tuning the luminescence properties that are in transition metal dichalcogenide (TMDC) monolayers is established and reveals that the doping effects in the high-carrier-density regimes are potentially significant for efficient optical modulation in monolayer semiconductors.
Electroluminescence from multi-particle exciton complexes in transition metal dichalcogenide semiconductors
Electroluminescence generated by a pulsed gate voltage from excitons, trions, and biexcitons in monolayer WSe2 and WS2 encapsulated with hBN, found to be as narrow as 2.8 meV.

Recently, the celebrated Keldysh potential has been widely used to describe the Coulomb interaction of few-body complexes in monolayer transition-metal dichalcogenides. Using this potential to model
Diversity of trion states and substrate effects in the optical properties of an MoS2 monolayer
An abinitio many-body formalism is developed to investigate the full spectrum of negative and positive trions in these layered semicondutors to explain recently found experimental splittings of the lowest trion line as well as excitation red-shifts on substrates.
Defects activated photoluminescence in two-dimensional semiconductors: interplay between bound, charged, and free excitons
This work investigates effects of anion vacancies in monolayer transition metal dichalcogenides as two-dimensional (2D) semiconductors where the vacancies density is controlled by α-particle irradiation or thermal-annealing and finds a new, sub-bandgap emission peak as well as increase in overall photoluminescence intensity as a result of the vacancy generation.
