  Interlayer excitons (IXs) are Coulomb-bound electron-hole pairs that occur in2D semiconductor heterostructures. Controlling the flow of IXs can lead todissipationless excitonic circuits due to the bosonic nature of the IXquasiparticle. Here, we report diode-like directed transport of IXs and anoptically gated IX transistor. Our results are enabled by a nanopatternedgraphene gate to create a smoothly varying potential slide within an MoSe2-WSe2heterostructure. Using photoluminescence (PL) measurements, we measure shiftingIX energy with position and a drift velocity of 1,600 m/s. Additionally, IXflow can be optically gated by saturating IX population with a second laserpulse, demonstrating an excitonic transistor via IX-IX repulsion. Our workpaves the way towards low loss valleytronic circuits based on IXs in 2Dheterostructures.[Journal_ref: ]

  More info

  Monolayer transition metal dichalcogenide (TMD) semiconductors such asMoSe$_2$ host strongly bound excitons which are known to exhibit a strongresonant third-order nonlinear response. Although there have been numerousstudies of the ultrafast nonlinear response of monolayer TMDs, a study of thesteady-state nonlinear response is lacking. We report a comprehensive study ofthe steady-state two-color nonlinear response of excitons in hBN-encapsulatedmonolayer MoSe$_2$ at 7 K. We observe differential transmission (DT) signalsassociated with the neutral and charged exciton species, which is stronglydependent on the polarization of the pump and probe. Our results are comparedto a theoretical model based on a T-matrix formulation for exciton-exciton,exciton-trion, and trion-trion correlations. The parameters are chosen suchthat the theory accurately reproduces the experimental DT spectrum, which isfound to be dominated by two-exciton correlations without strong biexcitonbinding, exciton-trion attractive interactions, and strong spin mixing throughincoherent relaxation.[Journal_ref: ]

  MoSe2-WSe2 heterostructures host strongly bound interlayer excitons (IXs) which exhibit bright photoluminescence (PL) when the twist-angle is near 0° or 60°. Over the past several years, there have been numerous reports on the optical response of these heterostructures but no unifying model to understand the dynamics of IXs and their temperature dependence. In this letter, we perform a comprehensive study of the temperature, excitation power, and time-dependent PL of IXs. We observe a significant decrease in PL intensity above a critical temperature that we attribute to a transition from localized to delocalized IXs. We conclude that this temperature dependence is a result of IX-IX interactions, which is suppressed by the moiré potential trapping IXs at low temperature. Astoundingly, we find a simple inverse relationship between the IX PL energy and the critical temperature, which exhibits opposite power dependent behaviors for near 0° and 60° samples.

  More info

  A plasmonic modulator is a device that controls the amplitude or phase ofpropagating plasmons. In a pure plasmonic modulator, the presence or absence ofa pump plasmonic wave controls the amplitude of a probe plasmonic wave througha channel. This control has to be mediated by an interaction between disparateplasmonic waves, typically requiring the integration of a nonlinear material.In this work, we demonstrate the first 2D semiconductor nonlinear plasmonicmodulator based on a WSe2 monolayer integrated on top of a lithographicallydefined metallic waveguide. We utilize the strong coupling between the surfaceplasmon polaritons, SPPs, and excitons in the WSe2 to give a 73 percent changein transmission through the device. We demonstrate control of the propagatingSPPs using both optical and SPP pumps, realizing the first demonstration of a2D semiconductor nonlinear plasmonic modulator, with a modulation depth of 4.1percent, and an ultralow switching energy estimated to be 40 aJ.[Journal_ref: ]

  In monolayer semiconductor transition metal dichalcogenides, theexciton-phonon interaction is expected to strongly affect the photocarrierdynamics. Here, we report on an unusual oscillatory enhancement of the neutralexciton photoluminescence with the excitation laser frequency in monolayerMoSe2. The frequency of oscillation matches that of the M-point longitudinalacoustic phonon, LA(M). Oscillatory behavior is also observed in thesteady-state emission linewidth and in timeresolved photoluminescenceexcitation data, which reveals variation with excitation energy in the excitonlifetime. These results clearly expose the key role played by phonons in theexciton formation and relaxation dynamics of two-dimensional van der Waalssemiconductors.[Journal_ref: Chow et al., npj 2D Materials and Applications 1, 33 (2017) (https://www.nature.com/articles/s41699-017-0035-1)]
