Phys.org  March 31, 2023 Applying strong DC electric fields on the apex of a sharp metallic tip causes electrons to be emitted radially from the apex to vacuum magnifying the nanoscopic information on the apex, which serves as a field emission microscope (FEM). When depositing molecules on such a tip, peculiar electron emission patterns such as clover leaves appear. However, the source of these emission patterns has not yet been identified owing to the limited experimental information about molecular configurations on a tip. An international team of researchers (Japan, Germany, France) used fullerene molecules and characterized the molecule-covered tip by […]
