A research group headed by Sun Xiangnan, a scientist at the National Center for Nanoscience and Technology at the Chinese Academy of Sciences, has unveiled a groundbreaking discovery. They found that the orientation of the intramolecular dipole in molecular semiconductor materials has a profound impact on the hyperfine interaction, which in turn dictates the spin lifetime of the material. Leveraging this insight, the team meticulously designed the orientation of the intramolecular dipole to markedly diminish the hyperfine interaction. Consequently, they were able to elevate the room-temperature spin lifetime to an unprecedented 106 microseconds (μs), setting a new record at ambient temperatures. This significant achievement holds promise for catalyzing the development of room-temperature spin-based computational devices.
