简介：日本东京大学岩佐义宏教授和理化学研冗所的研冗小组置称，实验证明具有与石墨烯相同的原子构成为蜂窝状晶格结构的层状MoS2是一种优异的谷电子学意义上的新型低耗电器件用半导体材料。为降低耗电量，此前的研究集中在自旋电子方面，即半导体器件不用电荷，而是利用电子自旋，但近年来谷电子学研究比较引人注目。这是利用电子的另一个自由度“谷”，即由半导体晶体结构的对称性产生的电子流动及流动方式在左旋和右旋具有不同的性质。通过抑制因半导体结晶缺陷及杂质导致的能量损失，使电子自旋高效运动，从而减少电子器件的电力消耗。

简介：采用水热法设计构筑三维花状二硫化钼，并利用XRD、SEM、RAMAN、TG等测试方法对产物的结构和形貌进行了表征，进而作为正极材料组装成锌离子电池并对其进行电化学测试分析，在充放电电压区间为0．2-1．2V、电流密度为1．0A／g条件下，首次放电比容量可达63．9mAh／g，100次循环后其放电比容量保持在53．6mAh／g，容量保持率为83．9％。较高的比容量和循环稳定性使MoS2成为有前景的锌离子电池正极材料之一。
