In this context, the lattice matched system CaF2/Si/CaF2 as prototype of a well controlled and ordered Si-based system with known microscopic structure is proposed. For this system, a new mechanism is found leading to a direct band gap based on the coupling of interface states in very thin Si layers. 关键词: MONOCLONAL ANTIBODY; COLORECTAL CANCER; LEUKOCYTE ADHERENCE INHIBITION; CARCINOEMBRYONIC ANTIGEN CARCINOEMBRYONIC ANTIGEN; SILICON
