Description
SEM is a microscope that uses electrons instead of light to form an image. The SEM uses electromagnets rather than lenses, the researcher has much more control in the degree of magnification. Field-emission scanning electron microscope provides ultra high resolution image down to 1 nm resolution thanks to the inherent brightness of field–emission electron gun.
