Field electron emission from amorphous carbon thin films grown by RF magnetron sputtering
Jeong-Tak Ryu,Shin-Ichi Honda,Mitsuhiro Katayama,Kenjiro Oura 한국물리학회 2005 Current Applied Physics Vol.5 No.4
Using a RF magnetron sputtering, amorphous carbon (a-C) and N-doped a-C (a-C:N) thin lms were fabricated as eld electronemitter. These thin lms were deposited on Si(001) substrate at several temperatures. The eld emission property was improved fora-C thin lms grown at higher substrate temperatures. Furthermore, a-C:N lm exhibits eld emission property better than that ofundoped a-C lm. These results are explained in terms of the change in surface morphology and structural properties of a-C lm..

Alpha-fetoprotein-producing gastric cancer is associated with poor prognosis because of frequent liver and lymph node metastasis. We present a case with synchronous liver metastasis who survived for 5 years. A 69-year-old man with upper abdominal pain was referred to our hospital. Gastrointestinal endoscopy revealed a Borrmann II-like tumor in the lower part of the stomach. Computed tomography revealed a tumor in the left lobe of the liver. Serum alpha-fetoprotein levels were markedly increased. We performed distal gastrectomy after administering oral tegafur/gimeracil/oteracil potassium and administered hepatic intra-arterial cisplatin injection. Liver metastasis showed partial response on computed tomography. Despite left hepatic lobectomy, further metastases to the liver and mediastinal lymph nodes became difficult to control. After sorafenib tosylate administration, stabilization of the disease was observed for 4 months. We conclude that hepatic intra-arterial chemotherapy and oral administration of sorafenib tosylate may potentially improve the prognosis in such cases.
