Experimentally Mapping the Molecular Pathways and Intermolecular Forces that Drive Elasticity in Flexible Crystals

W. Stoll, Johanna Koelbel, М. И. Петров, Lincoln Katleski et autres

Elastically flexible molecular crystals are an emerging class of advanced materials, driving innovation in fields ranging from electronics to medicinal applications. At the fundamental level, bulk material elasticity is governed by the nature of the intermolecular forces found in thematerial, whicharenotdirectlyprobedusingstructural(crystallographic)measurements.

Observation of Multi-Phonon Emission in Monolayer WS2 on Various Substrates

Eli R. Adler, Thy Doan Mai Le, Ibrahim Boulares, Robert K. Boyd et autres

Transition metal dichalcogenides (TMDs) have unique absorption and emission properties that stem from their large excitonic binding energies, reduced-dielectric screening, and strong spin–orbit coupling. However, the role of substrates, phonons, and material defects in the excitonic scattering processes remains elusive. In tungsten-based …

Cross‐Plane Carrier Transport in Van der Waals Layered Materials

Sina Najmaei, Mahesh R. Neupane, Barbara Nichols, Robert A. Burke et autres

The mechanisms of carrier transport in the cross-plane crystal orientation of transition metal dichalcogenides are examined. The study of in-plane electronic properties of these van der Waals compounds has been the main research focus in recent years. However, the distinctive physical anisotropies, …

Process Development for Reactive-Ion Etching of Molybdenum Disulfide (MoS2) Utilizing a Poly(methyl methacrylate) (PMMA) Etch Mask

Alexander L. Mazzoni, Alin C Chipara, Robert A. Burke, Barbara Nichols et autres

Abstract : Previously we have relied on a carbon tetraflouride (CF4) + oxygen (O2) reactive-ion etching recipe (15 sccm CF4, 5 sccm O2, and 200 W) to etch molybdenum disulfide (MoS2). To define locations to be etched, the common electron beam lithography …

Temperature-Dependent Plasmon–Exciton Interactions in Hybrid Au/MoSe2 Nanostructures

Inès Abid, Weibing Chen, Jiangtan Yuan, Arash Bohloul et autres

Combining localized surface plasmons and confined excitons in hybrid metallic/semiconductor nanostructures is a promising route toward the manipulation of the light–matter interaction at the nanoscale and the generation of novel technological applications. In this context, we investigate the interference between plasmonic and …
