Nonlinear optical response and spontaneous polarization in layer-stacked gallenene using second harmonic generation
Muhammad Yunusa, Andrew K. Schulz, Tim Parker +12
Gallenene is a promising low-dimensional material with a structure down to the thickness of a single atom, similar to graphene. However, van der Waals stacking of two-dimensional (…
Corrugation-dominated mechanical softening of defect-engineered graphene
Wael Joudi, Rika Saskia Windisch, Alberto Trentino +7
We measure the two-dimensional elastic modulus of atomically clean defect-engineered graphene with a known defect distribution and density in correlated ultra-high va…
Electron-irradiation effects on monolayer MoS2 at elevated temperatures
Carsten Speckmann, Kimmo Mustonen, Diana Propst +2
The effect of electron irradiation on 2D materials is an important topic, both for the correct interpretation of electron microscopy experiments and for possible applications in el…
Electron-beam-induced adatom-vacancy-complexes in mono- and bilayer phosphorene
Carsten Speckmann, Andrea Angeletti, Lukáš Kývala +7
Phosphorene, a puckered two-dimensional allotrope of phosphorus, has sparked considerable interest in recent years due to its potential especially for optoelectronic applications w…
Defect-engineering hexagonal boron nitride using low-energy Ar+ irradiation
Manuel Längle, Barbara Maria Mayer, Jacob Madsen +7
Monolayer hexagonal boron nitride (hBN) has recently become the focus of intense research as a material to host quantum emitters. Although it is well known that such emission is as…
Controllable Freezing Transparency for Water Ice on Scalable Graphene Films on Copper
Bernhard Fickl, Teresa M. Seifried, Erwin Rait +10
Control of water ice formation on surfaces is of key technological and economic importance, but the fundamental understanding of ice nucleation and growth mechanisms and the design…
