Predictable behavior of organic photovoltaic cells by Kelvin probe force microscopy
, 2013 International audienceWe investigate a new way to access to the open circuit voltage (Voc) of organicphotovoltaic (OPV) cells: the Kelvin probe force microscopy (KPFM). KPFM is apowerful technique, allowing mapping the surface potential above any surface

Kelvin Probe Force Microscopy (KPFM) for nanoelectronic device characterisation [PDF]
, 2016 This project is to develope a new method of characterization for Silicon-nano-wire (SiNW) FET and SET devices by using KPFM technology to derive the information of local surface potential change on the channel of SiNW devices. The surface potential is related to many important parameters on material's surface, e.g.

In-situ correlative SEM/KPFM for semiconductor devices and 2D heterostructures
Correlative nanoscale surface characterization benefits from simultaneously measuring electronic and structural properties in the same environment, a capability that is essential for modern-day materials science and semiconductor failure analysis. In-situ AFM-SEM measurements facilitated by self-sensing cantilevers offer great potential here; however ...

NanomaterialsDrug delivery vehicles composed of lipids and gemini surfactants (GS) are promising in gene therapy. Tuning the composition and properties of the delivery vehicle is important for the efficient load and delivery of DNA fragments (genes). In this paper, we studied novel gene delivery systems composed of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), 1,
