Connecting chirality and spin in electronic devices

摘要: Our lives have been transformed by the rapid development of electronics industry, but that pace has recently slowed down due to fundamental limits conventional silicon-based technologies. A promising candidate for next-generation is spintronics. It uses magnetic property electrons, spin, in addition their conventionally used electrical charge, process digital information. challenge spintronics efficiently convert between spin and charge signals, which currently relies on bulk properties materials. Recent research found an alternative approach this — using chiral molecules. These are molecules whose shape not mirror-symmetric, so they cannot be made exactly overlap with own mirror image. Their spin–charge conversion termed chirality-induced selectivity (CISS), reported various experiments involving spintronic devices. However, understanding observed signals lacking, underlying mechanism CISS still remains unclear. This thesis focuses manifestations Theoretically, it answers questions how when can generate such detected, what these imply about Experimentally, explores phenomena electronic devices introduced solid-state bio-organic The results presented only provide operation principles design guidelines CISS-based devices, also shed light link chirality
