Spatially resolved Raman spectroscopy of single- and few-layer graphene

D. Graf, F. Molitor, K. Ensslin, C. Stampfer, A. Jungen, C. Hierold, L. Wirtz

We present Raman spectroscopy measurements on single- and few-layer graphene flakes. Using a scanning confocal approach we collect spectral data with spatial resolution, which allows us to directly compare Raman images with scanning force micrographs. Single-layer graphene can be distinguished from…

Enhanced spatial resolution of MALDI images using silicon masks

Nicolas Verplanck, Maxence Wisztorski, Jonathan Stauber, J.C. Camart, Michel Salzet, Isabelle Fournier, Vincent Thomy

This paper reports on simple, efficient and economical methods to increase MALDI image resolution. It is not currently possible to focus the diameter of a MALDI laser down to 50x50µm², i.e. 2500µm², without decreasing signal intensity. But using Silicon masks openings features, it might even be…

Tunability of ferroelectric varactors up to 60GHz

Ludovic Burgnies, Gabriel Vélu, Karine Blary, Jean-Claude Carru, Didier Lippens

A TRL-multiline de-embedding technique for the determination of the electrical parameters of interdigitated varactors over a broad centimetre–millimetre band is proposed. The method is applied to voltage-controlled ferroelectric (BaSrTiO3) varactors, which exhibit almost constant frequency…
