Preparation of Thin Crystals of FeTe1-xSx Using the Scotch-Tape Method
  We have investigated an applicability of the scotch-tape method to fabricating thin crystals of Fe chalcogenide FeTe1-xSx. Thin crystals with a typical thickness of 40 nm were expectedly left on a Si substrate. Thin films prepared using this process will develop both detailed studies on intrinsic nature of Fe-based superconductivity and application to superconducting devices.
