Title: Control of excitons in multi-layer van der Waals heterostructures

Abstract

Here, we report an experimental study of excitons in a double quantum well van der Waals heterostructure made of atomically thin layers of MoS₂ and hexagonal boron nitride. The emission of neutral and charged excitons is controlled by gate voltage, temperature, and both the helicity and the power of optical excitation. Van der Waals heterostructures composed of ultrathin layers of transition metal dichalcogenides (TMD), such as MoS₂, WSe₂, etc., offer an opportunity to realize artificial materials with designable properties, forming a new platform for studying basic phenomena and developing optoelectronic devices. In the TMD structures, excitons have high binding energies and are prominent in the optical response. The energy, intensity, and polarization of exciton emission give information about the electronic, spin, and valley properties of TMD materials.

Voltage-controlled long-range propagation of indirect excitons in a van der Waals heterostructure

Journal Article Fowler-Gerace, L. H. ; Choksy, D. J. ; Butov, L. V. - Physical Review. B

Indirect excitons (IXs), also known as interlayer excitons, can form the medium for excitonic devices whose operation is based on controlled propagation of excitons. Here, a proof of principle for excitonic devices was demonstrated in GaAs heterostructures where the operation of excitonic devices is limited to low temperatures. IXs in van der Waals transition-metal dichalcogenide (TMD) heterostructures are characterized by high binding energies making IXs robust at room temperature and offering an opportunity to create excitonic devices operating at high temperatures suitable for applications. However, a characteristic feature of TMD heterostructures is the presence of moiré superlattice potentials, which aremore »« less

Indirect excitons in van der Waals heterostructures at room temperature

Journal Article Calman, E. V. ; Fogler, M. M. ; Butov, L. V. ; ... - Nature Communications

Indirect excitons (IXs) are explored both for studying quantum Bose gases in semiconductor materials and for the development of excitonic devices. IXs were extensively studied in III–V and II–VI semiconductor heterostructures where IX range of existence has been limited to low temperatures. Here, we present the observation of IXs at room temperature in van der Waals transition metal dichalcogenide (TMD) heterostructures. Here, this is achieved in TMD heterostructures based on monolayers of MoS2 separated by atomically thin hexagonal boron nitride. The IXs we realize in the TMD heterostructure have lifetimes orders of magnitude longer than lifetimes of direct excitons inmore »« less

Moiré potential impedes interlayer exciton diffusion in van der Waals heterostructures

Journal Article Choi, Junho ; Hsu, Wei-Ting ; Lu, Li-Syuan ; ... - Science Advances

The properties of van der Waals heterostructures are drastically altered by a tunable moiré superlattice arising from periodically varying atomic alignment between the layers. Exciton diffusion represents an important channel of energy transport in transition metal dichalcogenides (TMDs). While early studies performed on TMD heterobilayers suggested that carriers and excitons exhibit long diffusion, a rich variety of scenarios can exist. In a moiré crystal with a large supercell and deep potential, interlayer excitons may be completely localized. As the moiré period reduces at a larger twist angle, excitons can tunnel between supercells and diffuse over a longer lifetime. The diffusionmore »« less

Hybridized Exciton-Photon-Phonon States in a Transition Metal Dichalcogenide van der Waals Heterostructure Microcavity

Journal Article Li, Donghai ; Shan, Hangyong ; Rupprecht, Christoph ; ... - Physical Review Letters

Excitons in atomically thin transition-metal dichalcogenides (TMDs) have been established as an attractive platform to explore polaritonic physics, owing to their enormous binding energies and giant oscillator strength. Basic spectral features of exciton polaritons in TMD microcavities, thus far, were conventionally explained via two-coupled-oscillator models. This ignores, however, the impact of phonons on the polariton energy structure. Here we establish and quantify the threefold coupling between excitons, cavity photons, and phonons. For this purpose, we employ energy-momentum-resolved photoluminescence and spatially resolved coherent two-dimensional spectroscopy to investigate the spectral properties of a high-quality-factor microcavity with an embedded WSe₂ van der Waalsmore »« less

Persistent photoconductivity in two-dimensional Mo_1-xW _xSe₂–MoSe₂ van der Waals heterojunctions

Journal Article Puretzky, Alexander A. ; Basile, Leonardo ; Idrobo, Juan Carlos ; ... - Journal of Materials Research

Van der Waals (vdW) heterojunctions consisting of vertically-stacked individual or multiple layers of two-dimensional (2D) layered semiconductors, especially the transition metal dichalcogenides (TMDs), are fascinating new artificial solids just nanometers-thin that promise novel optoelectronic functionalities due to the sensitivity of their electronic and optical properties to strong quantum confinement and interfacial interactions. Here, monolayers of n-type MoSe₂ and p-type Mo_1-xW _xSe₂–MoSe₂ are grown by vapor transport methods, then transferred and stamped to form artificial vdW heterostructures with different interlayer orientations. Atomic-resolution Z-contrast electron microscopy and electron diffraction are used to characterize both the individual monolayers and the atomic registry betweenmore »« less
