Abstract CrP has many exotic physical properties due to a four-fold degenerate band crossing at the Y point of the Brillouin zone, which is protected by the nonsymmorphic symmetry of the space group. We carried out the heat capacity, electrical and thermal transport measurements on CrP and extracted the electron thermal conductivity. Due to the difference in energy and momentum relaxation time during electron-phonon inelastic scattering, the normalized Lorentz number decreases below about 160 K. Below 25.6 K, the normalized Lorentz number begins to recover, which is due to the dominance of elastic scattering between electrons and defects at low temperatures.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
