Hello everyone,
I am a PhD student in physics specializing in scanning probe measurements, particularly STM break junction experiments on molecules. I am currently looking for a reliable supplier of gold-coated mica substrates, preferably in dimensions around 1cm x 1cm (or similar sizes).
If anyone has experience with good suppliers offering high-quality substrates suitable for this type of work, I would greatly appreciate your recommendations. Bonus points if they can ship to the EU!
Thank you in advance for your suggestions and insights.
Best regards, Jérémie Pirard
Dear Jeremie
It is not difficult to create these substrate at lab level. Just try to find thermal evaporation unit within your department. You need a thin aluminum layer (~5 nm) on your substrate and then you can coat a gold layer of your desired thickness. Initially, you have to optimize parameter but it is easily doable. Lab fabricated thin films are quite handy and cheaper alternative. Visit this website if you still wish to buy it commercially.
