在发展高能量分辨率扫描隧道谱的基础上,实现了基于自旋翻转的非弹性隧道谱,从而实现了对单自旋态的探测,并成功在单分子尺度上研究了自旋间的超交换作用.还探测到了磁性原子在超导能隙中诱导的多重束缚态,并利用这些束缚态在单原子尺度上研究了自旋间的相互作用,在实空间实现了对单个原子的化学识别.利用低温扫描隧道谱,证明生长在Si基片的单原子层厚的铅和铟薄膜为超导体,这是至今报道的最薄的超导体.
Based on the development of high-energy-resolution scanning tunneling spectroscopy, a non-elastic tunneling spectrum based on spin inversion is realized, and the single-spin state detection is achieved. Exchange, and also detected the multiple bound states induced by the magnetic atoms in the superconducting gap, and used these bound states to study the interaction between the spins at the single atomic scale and realize the chemical recognition of a single atom in the real space Using low temperature scanning tunneling spectroscopy, it has been demonstrated that the monolayers of lead and indium films grown on Si substrates are superconductors, the thinnest superconductor so far reported.
