“…As discussed before, for samples with P doping ratio R higher than 0.22, they are degenerate semiconductors with carrier concentration of 10 20 cm -3 , it is reasonable that the carrier transport characteristics in those samples are similar with metal-like materials. 33,34 …”

High conductive phosphorus-doped nano-crystalline Si embedded in Silicon-Carbide (SiC) host matrix (nc-Si:SiC) films were obtained by thermally annealing doped amorphous Si-rich SiC materials. It was found that the room conductivity is increased significantly accompanying with the increase of doping concentrations as well as the enhanced crystallizations. The conductivity can be as high as 630 S/cm for samples with the optical band gap around 2.7 eV, while the carrier mobility is about 17.9 cm2/ V·s. Temperature-dependent conductivity and mobility measurements were performed which suggested that the carrier transport process is strongly affected by both the grain boundaries and the doping concentrations.

“…[49][50][51] Figure 2 illustrates this process for PT, which can be p-doped or n-doped. Doping creates radical cations or anions, also referred to as positive or negative polarons, respectively, which are delocalized along the polymer backbone and are a proposed mechanism for conductivity.…”

This review covers recent advances in conjugated polymers and their application in energy storage. Conjugated polymers are promising cost-effective, lightweight, and flexible electrode materials. The operating principles of conjugated polymers are presented within the framework of their potential for energy storage. Special focus is given to polyaniline electrodes. Recent advances are reviewed including new methods of synthesis, nanostructuring, and assembly. Also, covered are applications that take full advantage of the mechanical properties of conjugated polymers and future applications of these novel materials.

“…Doping is an important technique to control the electrical properties of polymer layers: [9,10] it increases the conductivity by several orders of magnitude even at minimal doping concentration, [9,11,12] and decreases the charge injection barrier resulting from the position shift of Fermi level relative to the carrier level. [13][14][15] Recent research has demonstrated that molecule doping-induced tail state filling can also effectively suppress geminate charge recombination at donor-acceptor interface via charge transfer excitions in bulk heterjunction (BHJ) photovoltaic.…”

Abstract:The energy level alignment at molecule-doped conjugated polymer/electrode interface is investigated. We find regular plots with a constant thickness-independent displacement away from the original energy level alignment behavior of the pristine polymer at low to intermediate level for molecule-doped conjugated polymer/conducting substrate interfaces.We proposed that two combined processes control the energy level alignment: (i) equilibration of the Fermi level due to oxidation (or reduction) of polymer sites at the interface as per the integer charge transfer model and (ii) a double dipole step induced by image charge from the dopant-polymer charge transfer complex that cause a shift of the work function. Such behavior is expected to hold for all low to intermediate level doped organic semiconductor systems.
