Spot Profile Analysis Low Energy Electron Diffraction of Plasma-Enhanced Chemical Vapor Deposition Grown Epitaxial Few-Layer Graphene on Sapphire
Niels Ganser, Marko A. Kriegel, Umut Kaya +6
We demonstrate the use of high-resolution spot-profile analysis low-energy electron diffraction to determine the mean grain size of plasma-enhanced chemical vapor deposition grown…
Ultra-large polymer-free suspended graphene films
L. Kalkhoff, S. Matschy, A. S. Meyer +5
Due to its extraordinary properties, suspended graphene is a critical element in a wide range of applications. Preparation methods that preserve the unique properties of graphene a…
Isolating the Nonlinear Optical Response of a MoS Monolayer under Extreme Screening of a Metal Substrate
Tao Yang, Stephan Sleziona, Erik Pollmann +5
Transition metal dichalcogenides (TMDCs) monolayers, as two-dimensional (2D) direct bandgap semiconductors, hold promise for advanced optoelectronic and photocatalytic devices. Int…
Gas dependent hysteresis in MoS field effect transistors
F. Urban, F. Giubileo, A. Grillo +10
We study the effect of electric stress, gas pressure and gas type on the hysteresis in the transfer characteristics of monolayer molybdenum disulfide (MoS2) field effect transistor…
Manipulation of the electrical and memory properties of MoS field-effect transistors by highly charged ion irradiation
Stephan Sleziona, Aniello Pelella, Enver Faella +6
Field-effect transistors based on molybdenum disulfide (MoS) exhibit a hysteresis in their transfer characteristics, which can be utilized to realize 2D memory devices. This hy…
Ultrashort Ne Ion Pulses for Use in Pump-Probe Experiments: Numerical Simulations
P. Kucharczyk, A. Golombek, M. Schleberger +2
A time resolved experiment to investigate the ultrafast dynamics following an ion impact onto a solid surface requires an ultrashort ion pump pulse in combination with a properly s…
