abstract
Kondo-semiconducting gap of CeRhAs single crystal has been measured by break-junction tunneling. The observed largest gap at 4.2 K is 2Δ~0.5 eV, while smaller sizes below 0.3–0.4 eV are also reproducible. We present the temperature evolution of the gap and discuss the gap size in comparison with the other Kondo semiconductors.
