Quantum well states in fractured crystals of the heavy fermion material CeCoIn$_5$

14 Sep 2020 Gauthier Nicolas Sobota Jonathan A. Hashimoto Makoto Pfau Heike Lu Dong-Hui Bauer Eric D. Ronning Filip Kirchmann Patrick S. Shen Zhi-Xun

Quantum well states appear in metallic thin films due to the confinement of the wave function by the film interfaces. Using angle-resolved photoemission spectroscopy, we unexpectedly observe quantum well states in fractured single crystals of CeCoIn$_5$... (read more)
