Chemical solutions for CuS deposition

During my postdoctoral stay at the Physics Institute of BUAP one of my duties is the deposition of thin-film semiconductors. At this laboratory IFUAP-205, I have been doing chemistry activities like the preparation of precursors solutions. In Fig.1, I want to show you three vials with solutions of different molar concentrations used for copper sulfide thin-film deposition: Copper chloride (CuCl2), Sodium hydroxide (NaOH) and Thiourea (NH2CSNH2). These solutions were dissolved in deionized water and stirred using a magnetic plate. What I have learned here is that solutions should be prepared one day before or in the moment of the chemical…

This tip is useful for engineering and science bloggers who want to share their knowledge on the web. Here is the way I found. I recently tested it on the Blogger system, the purpose is to share science tutorials with you using the correct math way. Let's do it! Step 1: Add a new gadget to your blog and copy and paste the following script. <script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script> <script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script> Step 2: Write code in a new post following using latex language inside: Inline: \( latex code here \) Paragraph: \[ latex code here…
