Can nanosilicon be true direct band gap material
... Can silicon ever be a true direct bandgap semiconductor? The first observation of a new short-lived photoluminescence band from silicon nanocrystals offers fresh hope. Silicon is ubiquitous in the electronics industry but is unsuitable for optoelectronic applications because it has an indirect bandg ...

... Thus connecting dissimilar metals in either pure water or water with dissolved salts is a bad thing to do: corrosion cells appear that eat up the metal with the lower (more negative) corrosion potential. Worse news is to come: it is not necessary to have two metals: both anodic and cathodic reaction ...

Ferroelectric materials for solar energy conversion
... Voc is the potential difference developed across a cell (in the light) when the terminals are not connected (no current ow). This represents the maximum voltage which can be generated by the cell. Voc is limited (in a standard semiconductor junction) by the band gap of the absorber layer, with addit ...

4.1.5 hydrophilic coating materials
... The best hydrophilic properties were achieved both by the use of anionic surfactants, which are chemically bound to the hydrophilic network, and non-ionic surfactants, which remain diffusible in the matrix. The coatings show excellent adhesion on different substrates (glass, polycarbonate, polyester ...

fuel cell charge transport
... Charge transport completes the circuit in an electrochemical system, moving charges from the electrode where they are produced to the electrode where they are consumed. They are two major types of charges species: electrons and ions. The transport of electrons versus ions is fundamentally different, ...

Solid
Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma). It is characterized by structural rigidity and resistance to changes of shape or volume. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire volume available to it like a gas does. The atoms in a solid are tightly bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary ice) or irregularly (an amorphous solid such as common window glass).The branch of physics that deals with solids is called solid-state physics, and is the main branch of condensed matter physics (which also includes liquids). Materials science is primarily concerned with the physical and chemical properties of solids. Solid-state chemistry is especially concerned with the synthesis of novel materials, as well as the science of identification and chemical composition.
