The Scanning Electron Microscope (SEM) is a powerful tool that uses focused beams of high-energy electrons to scan the surface of samples, producing detailed, high-resolution images and providing valuable surface information. Its ability to create three-dimensional images and analyze microstructures makes it indispensable in various scientific fields, including materials science, biology, and nanotechnology.
An electron gun produces a focused beam of high-energy electrons.
The electron beam is directed onto the surface of the sample, causing interactions with the sample's atoms.
Various signals (secondary electrons, backscattered electrons, and X-rays) are emitted from the sample as the electron beam interacts with it.
Detectors capture these signals to form high-resolution images, displaying the sample's surface features in detail.
The emitted signals are processed to create a magnified image of the sample, allowing analysis at the nanometer scale.
A Gold (Au) Sputter Machine is a device used in materials science and surface engineering for the deposition of thin films of gold onto various substrates. This process is crucial for enhancing the properties of materials and enabling advanced imaging techniques in electron microscopy.
