  1. With the introduction of the dopants, the effective mass of carriers was changed and the seebeck coefficient was increased. at the mean time, the dopants reduced the forbidden energy gap, which changed the carrier concentration and thus increased electrical conductivity. by calculating the forbidden energy gap and electrical conductivity of mg2si specimen doped with different amount sb, the mechanism of transference changed abruptly at 625k

    在mg _ 2si熱電材料基體中摻雜te 、 sb元素后，在結構中引入了缺陷，增大了體武漢理工大學博士學位論文系中載流子有效質量，提高了seebeck系數;降低了體系導電活化能，提高了電導率，同時也降低了熱導率。
  2. Periodic dielectric structure. they can create a range of forbidden frequencies called photonic bandgap. photons with energy lying in the gap cannot propagate through the medium

    它是介質顆粒周期排列而成的人工材料，能夠產生光子帶隙，頻率落在帶隙內的光在晶體里沿任何方向都不能傳播。
