Development of Hybrid Electro-Electroless Deposit (HEED) Coatings and Applications
Electrodeposition can be achieved via electroplating, whereby current is applied to the work piece serving as the cathode, or by using an electroless deposition process, wherein the reductant is a co-dissolved species in the plating solution. Researchers in Canada have developed a combined deposition process, termed hybrid electro-electroless deposition (HEED) to deposit two metals. Read the rest.
“Time of Flight” Electrochemistry
Measurement of molecular diffusion coefficients is important in understanding and determining the kinetics of physical and chemical processes. Among the measurement techniques employed are those based on pulsed field gradient nuclear magnetic resonance spectroscopy, field flow fractionation, and electrochemistry. Read the rest.
Atomic Layer Deposition of High Quality HfO2 Using In-Situ Formed Hydrophilic Oxide as an Interfacial Layer
High-quality HfO2 is now the dominant high-κ oxide in mainstream manufacturing processing in the semiconductor industry. Atomic-layer deposition (ALD) is the deposition method of choice for ultra-thin, controlled HfO2 growth. For uniform ALD of HfO2 on silicon (Si), an interfacial oxide layer is always needed.

Evaluation of the SEI Using a Multilayer Spectroscopic Ellipsometry Model
The solid electrolyte interphase (SEI) plays a critical role in the performance and stability of Li-ion batteries. Formed at the anode by reduction of electrolyte solution components, the film is comprised of an inner layer (adjacent to the electrode) composed primarily of inorganic matter and an outer layer (adjacent to the electrolyte) composed of organic matter. Read the rest.
Acidic Buffer-Free Organic Solar Cells Using Vanadium-Doped Indium Oxide Anodes
Organic solar cells (OSCs) are comprised of thin layers of materials arranged to exploit their inherent properties that together enable the conversion of light into separated charge carriers and the flow of current. Conventional OSCs employ a poly(3,4-ethylene dioxylene thiophene):poly(styrene sulfonic acid) (PEDOT:PSS) buffer layer that enables increased hole extraction efficiency from the active layer, but owing to its acidity leads to eventual etching of the Sn-doped In2O3 (ITO) anode.
