The STM (Scanning Tunneling Microscopy) Profile calculation can be performed in Materials Studio using CASTEP by following these steps:
Prepare the input file: Start by creating a new calculation in Materials Studio and select CASTEP as the engine. Define the input parameters for the system, such as the crystal structure, the unit cell, and the number of atoms.
Define the STM parameters: Next, define the STM parameters such as the tip shape, the tip-sample distance, and the bias voltage.
Run the calculation: Run the CASTEP calculation with the defined parameters to generate the electronic structure of the system.
Generate the STM profile: Use the STM tool in Materials Studio to generate the STM profile based on the electronic structure obtained in step 3.
Analyze the results: Analyze the STM profile to obtain information about the surface morphology and electronic structure of the material.
Note that in order to perform an STM calculation, you need to have a good understanding of the electronic structure of the system, including the band structure, density of states, and electron density. These can be calculated using CASTEP or other electronic structure calculation engines.
