Charge Density Wave on Cu(111) at 5 K


Homebuilt Low Temperature Microscope

SPM 1000 Control System W/PLLPro AFM Controller

Description :
Cu(111) imaged with V=20 mV and I=0.3 nA. A defect at the top part of the image produces a standing charge wave with 10 pm corrugation. The underlying copper lattice displays 2 pm corrugation.
