Abstract
The element germanium is an important material for the solid state device fabrication and antibacterial applications. It has been widely used for the optoelectronic applications. Polyethylene terephthalate (PET) materials are organic substrate materials with high transparency. It is used to in flexible and bendable electronic device in present and future. In this study, antibacterial and surface properties of the germanium layer deposition with nano thicknesses were investigated. Germanium material was successfully deposited on PET substrate and antibacterial properties against to gram positive Staphylococcus aureus (ATCC29213) and gram negative Escherichia coli (ATCC11775) bacterias were tested. Germanium layer thickness was measured as 200 nm and grain size was calculated about 40 nm. Crystal formations of the deposited layer were determined as (022), (133) and (224) formation. According to to XRD and EDX analysis, it found that deposited germanium layer was not containing any impurity and chemical bonds to atoms of PET substrate. Moreover, surface analysis of deposited PET sample was realized by scanning electron microscopy and atomic force microscopy. Furthermore, surface roughness, grain height distribution, contact angle, transparency and absorbance values were determined in this paper.
