Dear QE developers, I found slides presented by Lorenzo Paulatto titled *"Ab Initio Simulation of Infrared and Raman Spectroscopy."*
As mentioned in the Raman tensor section, some limitations like it can be done only with LDA, norm-conserving pseudopotentials for non-metals. But it also stated that *we could enable it at our own risk for semimetals*. Can you please guide me on *how I can enable Raman tensor calculation for semimetal* because when I am using smearing in SCF and then doing phonon, it shows an error like *no elec. field with metals*. And without a smearing tag, SCF shows an error showing smearing needed for my semimetal system. I am unable to find out solutions to this problem. Thank You Regards Sumit Kukreti Ph.D. Scholar IIT Jodhpur India
