A smart microfour-point probe with ultrasharp in-plane tips.
We propose a smart microfour-point probe (micro4PP) with ultrasharp in-plane tips that are arranged in a square with a spacing of 20 microm. The micro4PP consists of a supporting cantilever and four subcantilevers. The subcantilevers are symmetrically suspended from the square frame at the end of the supporting cantilever. A thermal actuator based on the bimorph effect is also integrated on each subcantilever for functionalization of interest. The unique configuration of the four-terminal tips is very useful for versatile applications of the micro4PP.
