Abstract

Abstract. A novel measurement device for simultaneous high temperature measurements of the electrical conductivity and the Hall coefficient has been developed. Simulations were used to design a suitable screen-printed planar platinum heating structure that generates temperatures of up to 600  ∘ C by Joule heating. Simulations of the temperature distribution have been validated using thermal imaging. With the hardware setup of two permanent magnetic yoke systems with a magnetic flux density of ±760  mT, the electrical conductivity and the charge carrier densities of a silicon wafer and a gold film were measured, as examples of a typical semiconductor with low charge carrier densities but high mobility and a metal representing materials with very high charge carrier densities but moderate mobilities, respectively. Measurements were compared with data from the literature to validate the functionality of the novel, low-cost measurement device.

新型低成本设备,可同时测量室温至600时的电导率和霍尔系数 °C
摘要研制了一种同时测量高温电导率和霍尔系数的新型测量装置。利用模拟设计了一种合适的丝网印刷平面铂加热结构,该结构可通过焦耳加热产生高达600°C的温度。利用热成像技术对温度分布进行了模拟验证。在磁通量密度为±760mt的两种永磁yoke系统的硬件设置下,分别以低载流子密度高迁移率的典型半导体和高载流子密度中等迁移率的金属材料为例,测量了硅晶片和金薄膜的电导率和载流子密度。测量结果与文献数据进行比较,以验证新型低成本测量装置的功能。

期刊介绍: Journal of Sensors and Sensor Systems (JSSS) is an international open-access journal dedicated to science, application, and advancement of sensors and sensors as part of measurement systems. The emphasis is on sensor principles and phenomena, measuring systems, sensor technologies, and applications. The goal of JSSS is to provide a platform for scientists and professionals in academia – as well as for developers, engineers, and users – to discuss new developments and advancements in sensors and sensor systems.
