elektronmikroskoop, mille korral aatomteravik „ujub“ üle skaneeritava pinna; aatomteraviku mõõtmed mõne aatomdiameetri suurusjärgus, horisontaaleraldusvõime ca 0,2 nm, vertikaaleraldusvõime ca 0,01 nm, microscope which uses a probe with an "atomic micro-tip" floated, using superconducting levitation, over the surface being scanned; the top/surface is of order of atomic diameters so that the electron current obtained is through quantum mechanical tunneling; a horizontal resolution of ca 0.2 nm and a vertical resulution of ca 0.01 nm is obtained
