A metal-coated carbon nanotube (CNT) tip for scanning tunneling microscope (STM) has been developed. By pulsed laser deposition (PLD), a CNT attached to tungsten was uniformly coated with 3–6 nm of thin layer. The observation Si(111)-7×7 surface using the tungsten-coated demonstrated stable atomic imaging and potentiality spectroscopy (STS) measurement, which can be achieved from pristine stage. It that mechanical robustness flexibility were maintained by virtue
