Born from a passion for research in the area of atomic layer deposition (ALD), OkyayTech is building custom ALD tools for university researchers and industrial research groups. Our philosophy is to design tools that can make ALD technology accessible for all researchers. Therefore, in our tool design we emphasize reducing complexity and promoting easy use for our customers while providing best-in-class performance and customization driven by research needs. Patented plasma technology is the state-of-the-art for the lowest Oxygen contamination in ALD-grown Nitride films.
Atomic Layer Deposition has been around almost 50 years. ALD is a modified CVD technique where the reaction is split into two parts. Each ‘half-reaction’ is self-limiting and surface-only. After completion of the two half-reactions, a monolayer of film has been deposited on the surface.
OkyayTech was founded by scientists with more than 40 years of combined nanotechnology and ALD expertise. Over 300 published academic papers in the area of Atomic Layer Deposition.
Atomic Layer Deposition
Working principle goes back to 1934, dr. one of the fiber(fiber) production methods that allows Formhals to allow it to produce polymer filaments by applying electrostatic force (there are several patents for the method). It has been used for the purpose of producing nanofibers in recent years. It is very easy to set up the working principle and the experimental setup based on it: to create an electrically charged field using atomic layer deposition high voltage and to allow the polymer to scatter in the form of fibers and accumulate in the collector.
Although a good analogy is made by comparing the oscillation of the polymer in the electric field to the winding of a garden hose, it is useful to wear Ald Coatings a grounded cuff when working close to the assembly.
One of the electrodes coming from the power source Ald Meaning is connected to the tip of the syringe from which the polymer will come out, and the other is connected to the collector.
After a certain voltage is exceeded, which is approximately 15kV and above, a sufficient electric field is created and the surface tension of the molten polymer released Ald Technology into the environment is overcome by the repulsive electrostatic forces caused by the electric environment and a cone-shaped structure called a taylor cone is formed.
The fluid in the form of a jet charged from the tip of the taylor cone is spinning towards the collector. The resulting structure resembles a spider web.
how deposition works
The size of the fibers formed can be determined how deposition works by sem or tem. Diameters can drop up to 100 nm depending on different factors such as the polymer used, voltage, and concentration.
atomic layer deposition an overview
There is a need for a syringe containing the polymer melt, a collector, a power source, atomic layer deposition an overview and a syringe pump that causes the polymer to enter the electric field at the syringe tip using a certain pressure.
