Consequence of Localized Conduction Band States

Not what you're looking for?

It's my understanding that localized conduction band states lead to a reduced mobility and therefore reduce photocatalytic activity. Yet, in the attached article, the author mentions that "Such localization of 3d electrons would result high efficient photo-excitation on Ti site under UV irradiation; i.e. high efficient photocatalyst." How can localization be beneficial to photocatalytic activity?

(The article can also be found here on page 138: http://pfwww.kek.jp/pfacr/part_a/partA_full_text.pdf)

  • Physics of Electronic Devices and Circuits

    A single atom has electrons localized about itself. An atomic orbital of one atom may overlap with an atomic orbital of another atom forming two molecular orbitals.

  • Molecular Orbital Theory vs Valence Bond Theory: Conductivity

    The band gap is large in an insulator (> 5eV); the energy gap is too large for electrons to be promoted to the conduction band, thus it will not carry charge.

  • Valance Bands & Energy to Produce and Electron Hole Pair

    If there are N number of atoms in the metal, then there are N energy levels in a valence band and N energy states in empty conduction band. The overlapping of bands is shown in figure2, (which generally occurs in metals).

  • Characteristics of a Good Conductor or Insulator

    To be more precise, from an atomic or quantum physics point of view, we can say that for good conduction to occur, the electrons must have available to them unfilled energy states immediately adjacent to the Fermi surface.

  • Solid State Chemistry - Density, Absorption, Charge

    The conduction band is at a higher energy than the valence band. True or false? True False True. No electronic states lie between the conduction and valence bands in n-type silicon. True or false? True False False.
