Query: Room-Temperature Charge Stability Modulated by Quantum Effects in a
  Nanoscale Silicon Island   We report on transport measurement performed on a room-temperature-operating
ultra-small Coulomb blockade devices with a silicon island of sub-5nm. The
charge stability at 300K exhibits a substantial change in slopes and diagonal
size of each successive Coulomb diamond, but remarkably its main feature
persists even at low temperature down to 5.3K except for additional Coulomb
peak splitting. This key feature of charge stability with additional fine
structures of Coulomb peaks are successfully modeled by including the interplay
between Coulomb interaction, valley splitting, and strong quantum confinement,
which leads to several low-energy many-body excited states for each dot
occupancy. These excited states become enhanced in the sub-5nm ultra-small
scale and persist even at 300K in the form of cluster, leading to the
substantial modulation of charge stability.
