摘要

En 中文
We report solution-processed, highly conductive (resistivity 1.3-3.8m Omega cm), p-type amorphous A-B-O (A=Bi, Pb; B=Ru, Ir), processable at temperatures (down to 240 degrees C) that are compatible with plastic substrates. The film surfaces are smooth on the atomic scale. Bi-Ru-O was analyzed in detail. A small optical bandgap (0.2 eV) with a valence band maximum (VBM) below but very close to the Fermi level (binding energy E-VBM = 0.04 eV) explains the high conductivity and suggests that they are degenerated semiconductors. The conductivity changes from three-dimensional to two-dimensional with decreasing temperature across 25 K. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4754608]
