Theory of In-Plane-Magnetic-Field-Dependent Excitonic Spectra in Atomically Thin Semiconductors
Michiel Snoeken, Paul Steeger, Robert Schmidt +4
The linear absorption spectrum of excitons in TMDC monolayers under the influence of an in-plane magnetic field is theoretically studied. We demonstrate that in-plane magnetic fiel…
Efficient broadband terahertz generation by above band-gap excitation of the pyroelectric ZnSnN2
T. S. Seifert, H. Hempel, O. Gückstock +10
Terahertz (THz) radiation is a powerful probe of low-energy excitations in all phases of matter. However, it remains a challenge to find materials that efficiently generate THz rad…
Element-specific ultrafast lattice dynamics in monolayer WSe2
H. Jung, S. Dong, D. Zahn +8
We study monolayer WSe2 using ultrafast electron diffraction. We introduce an approach to quantitatively extract atomic-site-specific information, providing an element-specific vie…
Engineering 2D material exciton lineshape with graphene/h-BN encapsulation
Steffi Y. Woo, Fuhui Shao, Ashish Arora +20
Control over the optical properties of atomically thin two-dimensional (2D) layers, including those of transition metal dichalcogenides (TMDs), is needed for future optoelectronic…
High-performance broadband Faraday rotation spectroscopy of 2D materials and thin magnetic films
Benjamin Carey, Nils Kolja Wessling, Paul Steeger +8
We present a Faraday rotation spectroscopy (FRS) technique for measurements on the micron scale. Spectral acquisition speeds of many orders of magnitude faster than state-of-the-ar…
Strain-dependent exciton diffusion in transition metal dichalcogenides
Roberto Rosati, Samuel Brem, Raül Perea-Causín +5
Monolayers of transition metal dichalcogenides (TMDs) have a remarkable excitonic landscape with deeply bound bright and dark exciton states. Their properties are strongly affected…
Dark trions govern the temperature-dependent optical absorption and emission of doped atomically thin semiconductors
Ashish Arora, Nils Kolja Wessling, Thorsten Deilmann +7
We perform absorption and photoluminescence spectroscopy of trions in hBN-encapsulated WSe, WS, MoSe, and MoS monolayers, depending on temperature. The different tr…
Thickness determination of MoS2, MoSe2, WS2 and WSe2 on transparent stamps used for deterministic transfer of 2D materials
Najme S. Taghavi, Patricia Gant, Peng Huang +7
Here, we propose a method to determine the thickness of the most common transition metal dichalcogenides (TMDCs) placed on the surface of transparent stamps, used for the determini…
Biaxial strain tuning of the optical properties of single-layer transition metal dichalcogenides
Riccardo Frisenda, Matthias Drüppel, Robert Schmidt +5
Since their discovery single-layer semiconducting transition metal dichalcogenides have attracted much attention thanks to their outstanding optical and mechanical properties. Stra…
Photovoltaic and photothermoelectric effect in a double-gated WSe2 device
Dirk J. Groenendijk, Michele Buscema, Gary A. Steele +4
Tungsten diselenide (WSe2), a semiconducting transition metal dichalcogenide (TMDC), shows great potential as active material in optoelectronic devices due to its ambipolarity and…
