摘要

我们设计了用于氚探测的碳化硅 PIN 二极管原型。蒙特卡洛计算表明，有必要在真空中工作，并采用薄而低密度的镀膜层，同时绘制了器件中的能量沉积曲线。然后利用沉积能量进行有限元模拟，以优化三个结构参数（n-掺杂浓度、p-掺杂浓度、p 区厚度），最大限度地提高电气响应。降低温度可改善二极管的电气响应。

Silicon carbide PIN diode for tritium detection

We have designed a prototype of silicon carbide PIN diode for tritium detection. Monte-Carlo calculations showed the necessity to work in vacuum and employ thin and low-density coating layers, and drew the energy deposition profile in the device. The deposited energies have then been used to implement finite-elements simulations, in order to optimize three structural parameters (

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
