AC-KPFM 2020 - 2024

The knowledge of the electrical surface charge distribution at the nanoscale is beneficial for many research areas including biological and material sciences. Kelvin Probe Force Microscopy (KPFM) is considered an eligible tool for the quantitative determination thereof. Current methods utilize a DC-Bias for the measurement of the charge distribution, which is not desirable when operating in liquid environments or on semiconductors. This project aims to bypass the parasitic effects of current methods and to enable quantitative surface potential measurments in DC-Bias critical environments. Read more →

Atomic Force Microscopy using self-sensing cantilevers

In Atomic Force Microscopy (AFM), micro-cantilevers with a sharp tip are scanned over a sample to measure various surface properties with nanometer resolution. The measurement of the cantilever deflection is a crucial part, which defines the imaging performance of AFM. Self-sensing cantilevers with integrated piezoresistive or capacitive elements enable a direct and efficient deflection measurement and are a promising alternative to the conventional optical lever method. This project aims at enabling novel AFM methods and applications by exploiting the advantages of self-sensing cantilevers. Read more →
