2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS).
Carbon nanofibers contained nano cellulose were prepared and the resulting carbon nanofiber composites were characterized by electron microscopy, Brunauer-Emmett-Teller (BET) method and image analysis. The samples are also evaluated as electrodes of
