Superconductors are materials that conduct electricity with an electrical resistance of zero. Superconductivity is generally observed when materials are cooled down to extremely low temperatures. In ...

As world-wide demand for energy continues to increase, the need for energy sources that are free of green house gas emissions becomes even more pressing. Probably, the most successful such energy ...

In this work, using the AlO/STO heterostructure as a model system, we report on unique orbital symmetry and orbital occupancy, which is reversed compared with other well-known 2D electron gases based ...

Another perspective on spinel comes from looking at its unit shell (counter-intuitive, I know). First we show the Mg atoms, which form an fcc aray, plus 4 more atoms inside the cube. Those 4 are ...
