The general goal of this project is to understand the growth of ZnS on tabacco mosaic virus (TMV) with high-resolution low-voltage transmission electron microscopy in the voltage range between 20kV and 80kV. We apply our newly developed microscope which is corrected for the spherical and chromatic aberration of the objective lens showing sub-Angstroem resolution at 40kV. The obtained insights will help to control the size and shape of semiconductor nanoparticles, since this is essential for the synthesis of nano-sized functional material with tailored properties. To image the mineralization of inorganic material on organic components we must find optimum strategies and develop techniques in the field of TEM sample preparation and TEM imaging conditions in order to be able to understand the properties of the organic (TMV)/inorganic (ZnS, ZnO) interfaces.
In this contribution we present our first steps towards these aims
