Title: class STM
Post by: karolina2 on September 5, 2022, 18:59

Dear All,

I am wondering how to use STM class. There is no usage example in the manual.

The STM image can be simply calculated using LDOS of bulk configuration in Tersoff-Hamann approximation but it seems that STM class enables also to take into account tip  structure.

Could you kindly explain how to use STM class?

Did you check https://docs.quantumatk.com/tutorials/tamr_ldos/tamr_ldos.html, or do you need to go even further beyond that model?

Dear Anders,

Thank you. As far as I see, in the TAMR case study the STM tip structure is not considered. However,  class STM for which there is no usage example in the 2022 manual seems to have tip_configuration parameter that allows to read bulk configuration.

So l am wondering whether tip and sample configuration should be stored in separate
 files and then somehow read.

Yes they should. I will locate someone who can provide an example
