Silicon nanotubes are tube-like nanoparticles which are made of silicon atoms. They are similar to carbon nanotubes and widely used in the semiconductor industry due to their exceptional electromechanical properties. Silicon nanotubes are used in electronics as they contain hydrogen molecules and behave like a metal fuel.
