Electronic transport properties of graphene/Al2O3 (0001) interface
(2018-01-01)
The electronic structure and transport properties of a single layer of graphene (Gr) on α-Al2O3 surface are studied using the density functional theory (DFT). We present three models that take into account the atom at the ...
Potassium hexacyanoferrate(III): A promising additive for perovskite precursors in carbon-based perovskite solar cells
(ElsevierPE, 2023-06-13)
Perovskite solar cells (PSCs) that use carbon electrodes and low-temperature processed electron transport layers (ETLs) show great promise in meeting global energy needs at an affordable price. Our current research is ...
Eumelanin thin films: Solution-processing, growth, and charge transport properties
(2013-08-21)
Eumelanin pigments show hydration-dependent conductivity, broad-band UV-vis absorption, and chelation of metal ions. Solution-processing of synthetic eumelanins opens new possibilities for the characterization of eumelanin ...

Cationic disorder and Mn3þ/Mn4þ charge ordering in the B′ and B″ sites of Ca3Mn2NbO9 perovskite: a comparison with Ca3Mn2WO9
(Academic Press Inc Elsevier Science, 2013-10-30)
We describe the preparation, crystal structure determination, magnetic and transport properties of two novel Mn-containing perovskites, with a different electronic configuration for Mn atoms located in B site. Ca3Mn3+2WO9 ...
Structure-property correlations of synthetic eumelanin towards bioelectronic applications
(Universidade Estadual Paulista (Unesp), 2021-02-26)
The natural pigment known as melanin has become a very promising material for many technological applications, but especially in the emerging area of organic bioelectronics due to its charge transport properties and ...
Contribuições ao estudo do transporte eletrônico em nanofios semicondutores : localização e estados de interface
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2013-04-11)
In this work, we studied the influence of surface charges on the properties (especially electronic transport) of semiconductor nanowires and nanobelts via computer simulations and also they were compared to experimental ...
