B-factor notes

✎ This article/section is a stub — some half-sorted notes, not necessarily checked, not necessarily correct. Feel free to ignore, or tell me about it.

B-factor (a.k.a. Debye–Waller factor (DWF), temperature factor) relates to the fact that at higher temperatures, atoms will displace from their mean position more.

For example:

• in atomic structures, each atom may have a B-factor (as e.g. in PDB structures[1])
• in X-ray scattering, temperature factor will mean the peak will be lower
• in Transmission EM images, it will bias away from high frequency information
