摘要：

We present a photoemission and x-ray-absorption study on boron carbide which identifies the spectroscopic features of this material, discussing them in connection with current structural models. A study on the surface thermal stability is also performed, revealing that despite the high melting point of boron carbide (similar to 2600 K), significant surface modifications occur in the material at about 1800 K. At this temperature the surface becomes covered with a graphite layer formed from bulk segregation of carbon, leaving boron-rich boron carbide buried beneath the graphitic surface.
