Determinação das energias de superfície do SnO2 puro e dopado Surface energy of pure and doped tin oxide

open access: yesCerâmica, 2009
A calorimetria tem se mostrado uma importante ferramenta para o controle e entendimento de comportamentos de sistemas nanoestruturados. Isto se deve basicamente às recentes medidas de energia de superfície reportadas na literatura; isto é, como em ...

Influence of Adsorption of Dopant on Distribution of the Dopant in A P-N-Junction [PDF]

open access: yesUniversal Journal of Applied Science, 2013
It has been shown, that manufacturing diffu- sive- and implanted-junction rectifiers in a semiconductor heterostructure and optimization of annealing give us possi- bility to increase sharpness of p-n-junction and homogeneity of dopant distribution in doped area.

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

Phase composition of Bi2O3 specimens doped with Ti, Zr and Hf [PDF]

open access: yesJournal of the Serbian Chemical Society, 2012
Powder mixtures of α-Bi2O3 containing 2, 5 and 10 mole % of TiO2, ZrO2 or HfO2 were homogenized, heated at 820ºC for 24 h and quenched in air. X-ray powder diffraction technique was used to characterize the prepared samples.

MODELING OF REDISTRIBUTION OF INFUSED DOPANT IN A MULTILAYER STRUCTURE DOPANT UNDER INFLUENCE OF VARIATION OF PRESSURE OF VAPOR OF THE DOPANT

open access: yes, 2020
In this paper we used an analytical approach to model nonlinear diffusion of dopant in a multilayer structure with account nonstationary annealing of the dopant. The approach do without crosslinking solutions at the interface between layers of the multilayer structure.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...
