Effect of Chamber Ultimate Pressure on Carbon Coating

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Effect of Chamber Ultimate Pressure on Carbon Coating Electron microscopy is a method to image samples, which provides much higher resolution and further details compared to traditional optical microscopes. Samples should be conductive for this analysis, so a conductive layer is normally deposited on the sample surface to image nonconductive surfaces. Carbon is one of the common materials used for sample preparation for electron microscopy, but carbon coating needs a vacuum chamber to reach required conductivity [1].

In this method, the high-power pulsed laser beam focuses on the target that is inside the vacuum chamber. The target material is vaporized by a laser beam in the form of a Plasma Plume and deposit on the substrate as a thin film. This process can be performed in a high vacuum environment or in an environment with background gases such as oxygen. Oxygen is usually used for the oxide deposition to completely oxygenate the deposited thin film during the pulsed laser deposition (PLD) process. Figure 1 shows the PLD mechanism of operation.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Carbon Coating for EM and EDX Sample Preparation Electron microscopes and analytical methods using X-rays are powerful tools that provide valuable information at the nanoscale of various samples. Some samples need to undergo a preparation step before being analyzed. The first group of samples that need to be prepared are radiation-sensitive samples. This group of samples comprises most biological samples, but other sensitive materials, such as plastics, are also included. The second groups of samples that need to be prepared are non-conductive materials or materials with poor electrical conductivity.

Ultra-High Vacuum Systems

Carbon Coater, Pulsed Laser deposition, Sputter Coater, Thermal evaporation

[vc_row][vc_column width="1/4"][vc_wp_posts number="10"][/vc_column][vc_column width="3/4"][vc_column_text] Ultra-High Vacuum Systems Since vacuum means no material, what is actually measured as vacuum, is the residual gas pressure in the chamber. Three different units of expression are usually used to express the pressure: Pascal(Pa), Torr, and bar. Vacuum quality is also usually classified into three categories: Rough Vacuum, High Vacuum and Ultra-High Vacuum. Ultra-High Vacuum(UHV) is called pressure range less than 10-7 Pascal or 10-9 Torr. Classification of different vacuum levels When an ionic or electron beam collides with particles(residual gas inside the chamber), it may deviate from its path, divide or even react with that particle. As a result, the presence of unwanted particles in the system will reduce its efficiency. Mean Free Path(MFP) is the average distance traveled by a gas molecule before…
