摘要：

We have carried out angle resolved photoemission spectroscopy of SmTe3, a quasi-two-dimensional material with an incommensurate high-temperature charge density wave (CDW). This is the first direct experimental view of the full detail of an imperfectly nested Fermi surface, and the momentum space gap anisotropy, for an incommensurate CDW.
