Catalytic Activity of Defect-Engineered Transition Metal Dichalcogenides Mapped with Atomic Scale Precision by Electrochemical Scanning Tunneling Microscopy

Autor: Lunardon, M., Kosmala, T., Ghorbani Asl, M., Krasheninnikov, A., Kolekar, S., Durante, C., Batzill, M., Agnoli, S., Granozzi, G.

Publikováno v: ACS Energy Letters 8(2023), 972-980

Unraveling structure–activity relationships is a key objective of catalysis. Unfortunately, the intrinsic complexity and structural heterogeneity of materials stand in the way of this goal, mainly because the activity measurements are area-averaged

A van der Waals Heterostructure with an Electronically Textured Moiré Pattern: PtSe₂/PtTe₂

Autor: Li, J., Ghorbani Asl, M., Lasek, K., Pathirage, V., Krasheninnikov, A., Batzill, M.

Publikováno v: ACS Nano 17(2023)6, 5913-5920

The interlayer interaction in Pt-dichalcogenides strongly affects their electronic structures. The modulations of the interlayer atom-coordination in vertical heterostructures based on these materials are expected to laterally modify these interlayer

Controlling stoichiometry in ultrathin van der Waals films: PtTe₂, Pt₂Te₃, Pt₃Te₄, and Pt₂Te₂

Autor: Lasek, K., Ghorbani Asl, M., Pathirage, V., Krasheninnikov, A., Batzill, M.

Publikováno v: ACS Nano 16(2022), 9908-9919

The platinum-tellurium phase diagram exhibits various (meta)stable van der Waals (vdW) materials, that can be constructed by stacking PtTe2 and Pt2Te2 layers. Mono phase PtTe2, being the thermodynamically most stable compound, can readily be grown as

Edge and Point-Defect Induced Electronic and Magnetic Properties in Monolayer PtSe₂

Autor: Li, J., Joseph, T., Ghorbani Asl, M., Kolekar, S., Krasheninnikov, A., Batzill, M.

Publikováno v: Advanced Functional Materials 32(2022)18, 2110428

Edges and point defects in layered dichalcogenides are important for tuning their electronic and magnetic properties. By combining scanning tunneling microscopy (STM) with density functional theory (DFT), the electronic structure of edges and point d

Water dissociation and association on mirror twin boundaries in two-dimensional MoSe2

Autor: Joseph, T., Ghorbani-Asl, M., Batzill, M., Krasheninnikov, Arkady

The adsorption and dissociation of water molecules on two-dimensional transition metal dichalcogenides (TMDs) is expected to be dominated by point defects, such as vacancies, and edges. At the same time, the role of grain boundaries, and particularly

Mirror twin boundaries in MoSe₂ monolayers as one dimensional nanotemplates for selective water adsorption

Autor: Li, J., Joseph, T., Ghorbani Asl, M., Kolekar, S., Krasheninnikov, A., Batzill, M.

Publikováno v: Nanoscale 13(2021)2, 1038-1047

Water adsorption on transition metal dichalcogenides and other 2D materials is generally governed by weak van der Waals interactions. This results in a hydrophobic character of the basal planes, and defects may play a significant role in water adsorp
