Abstract
Electronic circuit elements that show analog resistance change are required for the development of hardware-based machine learning systems. The energy level of a molecular orbital changes when the bond angle is distorted, for example when using a C60 molecule that is compressed by a scanning tunneling microscope (STM). The issue for practical use of this phenomenon is how to compress a C60 molecule in actual devices. In this study we have developed an electrochemical method in which Ag atoms precipitated from a Ag2S electrode compress a C60 molecule. We measured the I/V characteristics of a C60 molecule using a STM equipped with a Ag2S tip. The I/V characteristics clearly show the change in electronic states of the C60 molecule due to compression by the precipitated Ag atoms. Since this method can be implemented in actual devices, a Ag2S-C60 system will be a candidate element for future machine learning systems.
