| Abstract: | As one of the options for the energy conversion between thermal and electrical energy,thermoelectric materials are widely used as clean,reliable,and sustainable energy sources.Recent theoretical and experimental studies have demonstrated that it is promising to decrease the dimensions and the sizes in the research and development of thermoelectric materials.The low-dimensional configuration can increase in the density of states at Fermi energy greatly.With the crystal size decreasing from micron-meter to na... |
