摘要：

One-dimensional (1D) quantum wells are coated on a Si(001)-c(4x2) surface. A pair of straight Al ad-dimer chains works as potential walls for the confinement of surface-state electrons on the Si(001) surface. The quantum properties of the 1D quantum wells are directly probed by low-temperature scanning tunneling microscopy and spectroscopy. They are well described by size quantization of electrons in the unoccupied pi* surface states of the Si(001)-c(4x2) surface, based on the "1D particle-in-a-box" model. [S0163-1829(99)11719-3].
