抄録

Nanometric tip diameter fiber probes for photon scanning tunneling microscopes (PSTM) were fabricated by selective chemical etching of GeO 2 -doped optical fibers. The cone angle θ of the fiber probe tip was controlled by varying the doping ratio of the fiber core and the composition of the etching solution, and the standard deviation of the cone angle Δθ was within 0.5°. A fiber probe with θ=20° and tip diameter of less than 10 nm was fabricated. This is, to the authors' knowledge, the sharpest PSTM probe which has ever been reported.
