英文摘要REB2C2 (RE = Y and lanthanides) compounds have gained attention for their unique layered crystal structure. However, there have been few reports about Raman spectroscopy of REB2C2 compounds up to now. Here, the Raman spectrum of YbB2C2 is obtained by a micro-Raman spectroscope and the first-principles calculations. Raman active vibrational modes of YbB2C2 are confirmed as A(1g) (627 and 1311 cm(-1)), B-1g (944 and 1172 cm(-1)), B-2g (330 and 885 cm(-1)) and E-g (357 and 530 cm(-1)). Atomic displacements of these modes are different, they can be divided into two groups: A(1g), B-1g and B-2g correspond to ring breathing (delta(in), in the plane) of B2C2 layer; E-g is due to ring deformation (delta(oop), out of the plane) of B2C2 layer. These results are helpful to understand the individual structure of REB2C2.
