Design Principles of p-Type Transparent Conductive Materials

Abstract: Transparent conductive materials (TCMs) has always been playing a significant role in electronic and photovoltaic area, due to its prominent optical and electronic properties. To render those transparent materials highly conductive, efficient n-and p-type doping is critically needed to obtain high concentration of free electron and hole carriers. Despite extensive research over the past five decades, highquality p-type doping of wide-band-gap transparent materials remains a challenge. Here, we summarize four p… Show more

“…All atoms were allowed to relax until the force on each atom was less than 0.02 eV. For supercell calculations on point defects, the formation energy is given by [ 56 ] leftEformα,q=Eα,qEhost+ΣniEi+Σniμi+ qεnormalF+qεVBMhost where E (host) and E (α, q ) are the total energies of the perfect host system and the supercell containing the defect α in charge state q , respectively; E ( i ) is the energy of elemental solid or gas; μ i is the chemical potential of elemental species i referenced to E ( i ) and n i indicates the number of atoms added (negative sign) or removed (positive sign) from the supercell model. ε F represents the Fermi level and ε VBM (host) is the valence band maximum (VBM) of the host system.…”

“…For the best design of p-type TCOs, both experimental and theoretical data about the electronic structure of metal oxides should be taken into account [7][8][9]. In most metal oxides, the minimum of the conduction band (CBM) is formed by metallic s orbitals that are spatially extended.…”

“…On the other hand, the maximum of the valence band (VBM) is formed by oxygen 2p orbitals, which are quite localized, giving rise to a large effective mass for holes that results in very low mobilities for these charge carriers. Furthermore, the dispersion of the valence band tends to be small, and the VBM level is so deep that p-type doping is difficult [9].…”
