We describe a method of preparing gold scanning tunneling microscopy STM tips by direct currentelectrochemical etching in concentrated HCl and ethanol solution. Gold tips with tip apex radiuslower than 30nm can be reproducibly prepared by this method. The influence of the solutioncomposition, etching voltage on the surface structure, and sharpness has been investigated. Thesetips can be efficiently used for STM imaging, tip-enhanced Raman spectroscopy, and light emissioninvestigations on the same sample.
