Abstract
Disclosed is a method for producing and identifying a Weyl semimetal. Identification is enabled via a combination of the vacuum ultraviolet (low-photon energy) and soft X-ray (SX) angle resolved photoemission spectroscopy (ARPES). Production generally requires providing high purity raw materials, creating a mixture, heating the mixture in a container at a temperature sufficient for thermal decomposition of an impurity while preventing the possible reaction between the side walls of the container and the raw materials, depositing the resulting compound and a transfer agent onto the bottom surface of the ampule, differentially heating the ampule, and allowing a chemical vapor transport reaction to complete.
