| 1 | Modelling and fabrication of wide temperature range Al_(0.24)Ga_(0.76)As/GaAs Hall magnetic sensors显示文摘Silicon Hall-effect sensors have been widely used in industry and research fields due to their straightforward fabrication process and CMOS compatibility.However,as their material property limitations,technicians usually implement complex CMOS circuits to improve the sensors’performance including temperature drift and offset compensation for fitting tough situation,but it is no doubt that it increases the design complexity and the sensor area.Gallium arsenide(GaAs)is a superior material of Hall-effect device because of its large mobility and stable temperature characteristics.Concerning there is no specified modelling of GaAs Hall-effect device,this paper investigated its modelling by using finite element method(FEM)software Silvaco TCAD®to help and guide GaAs Hall-effect device fabrication.The modeled sensor has been fabricated and its experimental results are in agreement with the simulation results.Comparing to our previous silicon Hall-effect sensor,the GaAs Hall-effect sensor demonstrates potential and reliable benchmark for the future Hall magnetic sensor developments. | Hua Fan Huichao Yue Jiangmin Mao Ting Peng Siming Zuo Quanyuan Feng Qi Wei Hadi Heidari | 2022 | Journal of Semiconductors2022，43，3： | 0 |
| 2 | Electrochemical co-reduction of Y(Ⅲ)and Al(Ⅲ)in a fluoride molten salt system and electrolytic preparation of Y-Al intermediate alloys显示文摘In this study,a molten salt co-reduction method was proposed for preparing Y-Al intermediate alloys and the electrochemical co-reduction behaviors of Y(Ⅲ)and Al(Ⅲ)and the reaction mechanism of intermetallic compound formation were investigated by transient electrochemical techniques.The results show that the reduction of Y(Ⅲ)at the Mo electrode is a reversible electrochemical process with a single-step transfer of three electrons,which is controlled by the mass transfer rate.The diffusion coefficient of Y(Ⅲ)in the fluoride salt at a temperature of 1323 K is 5.0238×10^(-3)cm^(2)/s.Moreover,the thermodynamic properties associated with the formation of Y-Al intermetallic compounds were estimated using a steady-state electrochemical method.Y-Al intermediate alloy containing 92 wt%yttrium was prepared by constant current electrolysis at 1323 K in the LiF-YF_(3)-AIF_(3)-Y_(2)O_(3)(6 wt%)-Al_(2)O_(3)(1 wt%)system at a cathodic current density of 8 A/cm^(2)for 2 h.The Y-Al intermediate alloy is mainly composed ofα-Y2Al and Y phases.The development and application of this innovative technology have solved major technical problems,such as a long production process,high energy consumption,and serious segregation of alloy elements at this stage. | Guoqing Yu Lin Zhou Fengqin Liu Siming Pang Dehong Chen Hongliang Zhao Zhengping Zuo | 2022 | Journal of Rare Earths2022，40，12： | 0 |
