Journal ArticleDOI
Observation of electron–hole puddles in graphene using a scanning single-electron transistor
Jens Martin,Nitzan Akerman,G. Ulbricht,Timm Lohmann,Jurgen H. Smet,K. von Klitzing,Amir Yacoby,Amir Yacoby +7 more
TL;DR: In this article, a scanning single-electron transistor is used to map the local density of states and the carrier density landscape in the vicinity of the neutrality point, and it is shown that electron-hole puddles can be quantitatively accounted for by considering noninteracting electrons and holes.
Journal ArticleDOI
The nature of localization in graphene under quantum Hall conditions
Jens Martin,Jens Martin,Nitzan Akerman,G. Ulbricht,Timm Lohmann,K. von Klitzing,Jurgen H. Smet,Amir Yacoby,Amir Yacoby +8 more
TL;DR: The effect of disorder in conventional two-dimensional electron systems is usually described in terms of individual electrons interacting with an underlying disorder potential as discussed by the authors, but in this case, coulombic interactions between electrons must also be taken into account.
Journal ArticleDOI
Investigation of the shift of Raman modes of graphene flakes
Miroslav Haluska,Dirk Obergfell,Jannik C. Meyer,Giusy Scalia,Giusy Scalia,G. Ulbricht,Benjamin Krauss,Dong-Hun Chae,Timm Lohmann,M. Lebert,Martti Kaempgen,Martin Hulman,Jurgen H. Smet,S. Roth,K. von Klitzing +14 more
TL;DR: In this paper, the authors used Raman spectroscopy as sensitive tool for the characterization of graphene samples and observed diverse shifts in the position of the Raman mode close to 2650 cm -1 in various as-prepared graphene flakes.
Proceedings ArticleDOI
Monte Carlo transmission line modelling of multilayer optical coatings for performance sensitivity of a dichroic filter for the ARIEL space telescope
Vinooja Thurairethinam,Giorgio Savini,Mario De Lucia,G. Ulbricht,Gary John Hawkins,Eoin Baldwin,Deirdre Coffey,J. D. Piercy,Tom Ray +8 more
TL;DR: In this article , the authors used two-dimensional transmission line modeling to evaluate the transmittance of light through multilayer coatings deposited on a substrate material for given materials, angle of incidence and polarisation.
Journal ArticleDOI
Frequency Domain Multiplexing for Microwave Kinetic Inductance Detectors: Comparing the Xilinx ZCU111 RFSoC with the New 2x2 RFSoC Board
TL;DR: The Xilinx ZCU111 Radio Frequency System on Chip (RFSoC) is a promising solution for reading out large arrays of microwave kinetic inductance detectors (MKIDs) as discussed by the authors .
