Understanding quasi1D atomicscale nanowires from ab initio theory: Electron transport, optical and thermodynamical properties,Used
Delivery time: 8-12 business days (International)
Onedimensional (1D) electronic systems are currently intensively investigated for both fundamental and technological reasons. Highly anisotropic surface superstructures have attracted considerable attention in this context. An acutely studied model system of this kind is the ordered atomicscale array of selfassembled In nanowires that forms the Si(111)(4x1)In phase at room temperature. More than 10 years ago it was discovered that this nanowire array undergoes a reversible metalinsulator transition from (4x1) to (8x2) translational symmetry at T=120K. Despite intensive discussion in the scientific literature, both the phase transition's driving mechanism and low temperature groundstate with its associated properties remain strongly controversial. In the present work the In/Si(111)(4x1)/(8x2) nanowire array is investigated by means of stateoftheart ab initio computer simulations, revealing for the first time the origin and nature of the phase transition. The results demonstrate the enormous importance of entropy contributions to the stability of lowdimensional systems and provide an important addition to the 1930s' Peierls theorem.
