What is it about?
Chiral spintronics is of great fundamental and applied importance. Here, we draw attention to the possibility of using the silicon nanotubes for the nanoelectromechanical spintronics devices. Using the relativistic technique we study the electromechanical responses of nanotubes to the torsional deformation. The torsion deformation removes spin degeneracy and leads to the formation of spin gaps at the band edges. It works like a switch. The opposite twisting directions result in the opposite chirality of tubules and induce the opposite spin currents.

Why is it important?
The chiral spintronics is a field with great interest on searching for new chiral materials and devices with novel functionalities. We point on the silicon nanotubes which might have applications in the world of spintronics and nano-electromichanics.
Perspectives
The torsion deformation of the nonchiral silicon nanotubes works like a switch, the opposite twisting directions can induce the opposite spin currents. This result is of great impotance for design of the new spintronis units
