绝缘包覆工艺对铁基非晶磁粉芯性能的影响

, 2017
本文以气雾化法制备的球状(Fe_(0.76)Si_(0.09)B_(0.1)P_(0.05))_(99)Nb_1非晶粉末为对象,首先利用正硅酸乙酯的水解反应,在非晶粉末表面原位生成SiO_2绝缘包覆层,通过调节正硅酸乙酯的含量,可以控制非晶粉末表面SiO_2绝缘层的厚度。随后,在非晶粉末表面包覆2 wt%的环氧树脂,形成均匀的双层核壳结构包覆层,利用液压成型机,在1800 MPa的压强下,将复合粉末压制成外径20.3 mm,内径12.7 mm,厚度6.0 mm的环形磁粉芯 ...

半绝缘 GaAs的表面光伏谱研究

, 2000
利用表面光伏法(SPV)研究了半绝缘GaAs(SI-GaAs)的缺陷态。通过加直流光偏置测量了室温下带边以下的光伏响应，发现带隙内缺陷态的光伏响应主要是由于表面而形成载流子浓度梯度引起的，通过实验表明SPV是一种对SI ...
