A simple KPFM-based approach for electrostatic-free topographic measurements: the case of MoS$_2$ on SiO$_2$

Autor: Arrighi, Aloïs, Ullberg, Nathan, Derycke, Vincent, Grévin, Benjamin

A simple implementation of Kelvin probe force microscopy is reported that enables recording topographic images in the absence of any component of the electrostatic force. Our approach is based on a close loop z-spectroscopy operated in data cube mode

Field-effect transistor based biosensing of glucose using carbon nanotubes and monolayer MoS2

Autor: Ullberg, Nathan

As part of the EU SmartVista project to develop a multi-modal wearable sensor for health diagnostics, field-effect transistor (FET) based biosensors were explored, with glucose as the analyte, and carbon nanotubes (CNTs) or monolayer MoS2 as the semi

Monitoring the low doping regime in graphene using Raman 2D peak-splits: Comparison of gated Raman and transport measurements

Autor: Chen, Zhuofa, Ullberg, Nathan, Vutukuru, Mounika, Barton, David, Swan, Anna K

Avoiding charge density fluctuations and impurities in graphene is vital for high-quality graphene-based devices. Traditional characterization methods require device fabrication and electrical transport measurements, which are labor-intensive and tim
