High viscosity will make the colloid not effectively infiltrate the surface of the hollow fiber membranes, sealing is easy to produce bubbles and defects, leading membrane separator leakage;( 3) have a good heat resistance, pressure resistance and resistance to organic solvents. 粘度过高会使胶体无法有效浸润中空纤维膜表面,密封时易气泡和缺陷,导致膜分离器漏气;(3)具有良好的耐温、耐压和耐有机溶剂性。
Density of states results showed the existence of a large carrier concentration on both sides of the Fermi surface, which would induce large leakage current at ON state. Si doping can be used to increase the resistance. 态密度结果显示费米面两侧存在较高的载流子浓度,容易导致开态漏电流,可通过掺杂Si来增加阻值。
