Prof. Suto gave us a talk entitled "Physics of nanostructures revealed by hydrogen-terminated Si surfaces" on Nov. 21, 2019.
The talk is about hydrogen-terminated Si surfaces. The quality of the H-Si surfaces shown at his talk was surprisingly high.
They used a special procedure to make H-Si surfaces. I will visit him to learn the procedure.
Data from HREELS, STM were impressively beautiful (low noise, no contamination). Prof. Suto told me that they did the experiments repeatedly to find the best sample preparation conditions. And I suppose their experimental apparatuses were tuned to be in the best condition at the experiments.
From beautiful data, we can often make definite conclusion without speculation, and sometimes you will find something new in the data beyond your expectations.
There is an obvious difference between low-quality data from "Rush job" like experiments using experimental apparatuses tuned to minimum necessary condition and the high-quality data.
I have known that, but I was reminded of that by Prof. Suto's talk.
