Dear Hussam Bouaamlat (please sign always your posts to the forum with name and scientific affiliation) The negative or positive external potential applied to the STM tip roughly corresponds (if you neglect charging effects depending also on the tunneling current) to the offset between

[QE-users] Simulated STM

2021-03-23 Thread HUSSAM BOUAAMLAT
Dear QE users, I am trying to simulate STM images, the only problem I have is the bias voltage. in experimental we use, for example, V = 0.3 V, but when I use QE I have to use atomic units. So what is the value I need to get the same V = 0.3V value? I'm sorry if this question sounds trivial.
