<div><p dir="ltr">Dear CP2K users,</p><p dir="ltr">I am a beginner with CP2K and am currently working on STM simulations. I've been following the tutorial for simulating STM images of a graphene nanoribbon adsorbed on a metallic substrate, but I’m a bit confused by one step—it shows the metal substrate being removed from the system before the final calculation.</p><p dir="ltr">Is it standard practice to run the simulation on the molecule alone? Wouldn't excluding the substrate significantly change the electronic structure and the resulting images? I’m wondering if I can get reliable results by simulating the molecule in isolation, or if I should keep the metal atoms in the cell.</p><p dir="ltr">I would really appreciate any clarification or advice on this.</p><p dir="ltr">Best regards,</p><p dir="ltr">
