Oerlikon LEYBOLD vacuum extended the offer for research and experimental development system the process of chemical vapor deposition (CVD chemical vapor deposition) is from a variety of research and development laboratories used in particular for the synthesis of graph Kohlenstoffnanostrukturen, vertically aligned carbon nanotubes or silicon nanowires. Oerlikon LEYBOLD vacuum now offers a secure, simple and suitable to the immediate operating solution for this application. “Fast and easily reproducible experiments are essential in this Nanoworld of atom-thick layers. Prof. Dr.
Mark Hermann Rummeli illustrates the CVD cubes of Oerlikon LEYBOLD vacuum offers precisely these properties in the form of a very compact and reliable experimental system”, by the Center for integrated nanostructure Physics (CINAP) IBS of the Sungkyunkwan University in Suwon, Republic of Korea. The expert Institute for solid state and materials research Dresden holds the chemical vapor deposition for graphs research of the IFW (CVD) for one of the most reliable methods for the production of large-area Graphene layers on metal substrates with different carbon sources. CVD cube as a desktop unit allows the formation of Graphene layers (bilayer graphene BG) on a themoplastischen polymer as the solid carbon source the tabletop. This effect has been demonstrated by atomic force microscopy (atomic force microscopy AFM) and optical microscopy (optic microscopy OM). The application is paving the way for new experimental arrangements, in which different solid carbon sources including different polymer films and small molecules can be used as raw material.
Graph is a flat monolayer of awake arranged carbon atoms, which are two-dimensional packed. This Nano material was studied extensively in recent years due to its unique properties, including charge transfer, as well as its thermal, optical and mechanical advantages. A sustainable implementation of these Research results will lead to graph or graph-based materials, which will play an important role in the areas of transparent flexible electrodes, energy storage, chemical sensors and organic electrodes. The research showed among other things that the opto electrical properties depend very much of graphs from the target substrate. Therefore the dielectrics/graph systems able to replicate the properties of suspended Graphene, which overcome the inherent difficulties of this suspended samples is a topical issue in the rapidly evolving nanotechnology field are. The thermal CVD was successfully used in this experimental studies reactor of Oerlikon LEYBOLD vacuum. Through its CVD-Express software, the system allows a simple, step-by-step programming of each reaction step. In addition to the increased usability with Plug and-play functionality, the system provides the following benefits: precise, configurable mass flow control and real time tracking of controlled experiments. Software-controlled Fluid module ensuring evaporate liquid quantities and to the deployment of a large number of reagents as liquid feedstock. Complex experimental settings can be saved and load for reproducibility. Single zone temperatures of 1000 C for the oven, resistance heating and constant-temperature reaction zone. Security alarms. The CVD-cube is the most compact thermal CVD reactor on the market, specially constructed for the most demanding security standards by research laboratories.
