Abstract
Silver and copper tetracyanoquinodimethane (TCNQ) salts have been imaged using a scanning tunneling microscope (STM) and an atomic force microscope. Single crystal, polycrystalline thick films, and vacuum‐deposited thin films on highly oriented pyrolytic graphite molybdenum disulfide, silvered mica, and potassium chloride (KCl) were imaged in this study. Images of the AgTCNQ thin films grown on several of these substrates showed molecular‐level resolution. A previously reported field‐induced switching phenomenon of silver TCNQ has now been observed using a STM. These results may be the basis for developing a molecular‐based information storage system.Keywords
