Fusion scientists have developed a 'nano-scale sculpture technique'

A research team of fusion scientists has succeeded in developing a "nano-scale sculpture technique" to fabricate an ultra-thin film by sharpening a tungsten sample with a focused ion beam. This enables the nano-scale observation of a cross-section very near the top surface of the tungsten sample using a transmission electron microscope. The sculpture technique developed by this research can be applied not only to tungsten but also to other hard materials.
