Material contrast and surface charge removal in electron and ion microscopy. By adding a short wavelength UV LED illumination during a scanning electron microscopy (SEM), distortions of an image caused by surface charging are canceled when UV wavelength is close to the electron work function of the sample. Samples without conductive (metal) coating can be imaged by SEM without charging under UV illumination.
Nano-textured surfaces of Si and Ti made by plasma treatment show bactericidal action – “mechanical antibiotics”.
Ultra-short laser modification of material create new phases (including high-pressure and temperature phases) of materials with different chemical and optical properties used for fabrication micro-optical, opto-mechanical, and micro-fluidic applications.
