摘要：

Results of recent band calculations on SmB6, YbB12, Ce3Pt3Sb4 and CeNiSn support our previous prediction that the band gap appearing in their non-f reference systems correlates strongly with the origin of an energy gap in the mixed-valent rare-earth compounds. Based on these results, a more detailed model on the mechanism of the appearance of an energy gap is discussed.
