The Fe2+ atom embedded in a semiconductor exhibits a single non-degenerate ground state of zero magnetic moment. A team of scientists from the University of Warsaw has just shown that by using a sufficiently large strain, ...
An international research team has simplified the steps to create highly efficient silicon solar cells by applying a new mix of materials to a standard design. Arrays of solar cells are used in solar panels to convert sunlight ...
Oxygen is indispensable to animal and plant life, but its presence in the wrong places can feed a fire and cause iron to rust.
In what could prove to be a significant advance in the fabrication of graphene-based nanodevices, a team of Berkeley Lab researchers has discovered a new mechanism for assembling two-dimensional (2D) molecular "islands" that ...
Although they don't currently have as much conductivity, solid-state electrolytes designed for lithium-ion batteries (LIBs) are emerging as a safer alternative to their more prevalent—sometimes flammable—liquid-electrolyte ...
Current semiconductor technology is based on silicon, an inorganic semiconductor material in which impurity atoms are introduced or doped for use in electronic components to increase conductivity and tailor the electronic ...
In electronics, nothing works without transistors: they are the fundamental building blocks on which the logic circuits in our computer chips are based. They usually consist of silicon crystals, doped with other types of ...
In the production of power, nearly two-thirds of energy input from fossil fuels is lost as waste heat. Industry is hungry for materials that can convert this heat to useful electricity, but a good thermoelectric material ...
Hematite is an expensive, Earth-abundant photoactive material that can be used as a photoanode for water splitting devices. It offers attractive properties, such as a low band gap that allows it to theoretically satisfy the ...
Solid oxide fuel cells (SOFC), recently used as a power source for households in Japan, have several drawbacks such as high-cost, material degradation and long start-up time derived from high operating temperatures up to ...
