First-principles modeling techniques have shown remarkable success in predicting electronic band structures of materials. However, the computational costs make it challenging to use them for predicting band structures of semiconductor heterostructure

The need for magnetic 2D materials that are stable to the enviroment and have high Curie temperatures is very important for various electronic and spintronic applications. We have found that two-dimensional porphyrin-type aza-conjugated microporous p

Because of the importance of ferromagnetism at room temperature, we search for new materials that can exhibit a non-vanishing magnetic moment at room temperature and at the same time can be used in spintronics. The experimental results indicate that

The dramatic drop of about 2.5 orders of magnitude in the Zn vacancy magnetization with nanocrystal (NC) size was experimentally found in ZnO quantum dots in vacuum and air. We explain such an unusual behavior by the different contributions of spatia

In doped semiconductors and metals, the Seebeck coefficient or thermopower decreases monotonically with increasing carrier concentration in agreement with the Pisarenko relation. Here, we establish a fundamental mechanism to modulate and increase the
