| Research Abstract |
The thermal diode samples are fabricated by the gravity assisted pulse laser ablation method (GAPLA). GAPLA is one of the compositionally graded thin film fabrication methods that is combined pulsed laser deposition and high gravity effect. The purpose of this research is to investigate the thermal rectification by the mass gradient of thin film material. As a combination of a light element and a heavy element suitable for revelation of a thermal rectification effect, the GAPLA experiments of the compositionally gradientthin film of B-Bi were conducted. It is difficult to control the residual volume to the thin film of boron because of its very light weight, and has not resulted in realization of thermal rectification. However, the knowledge about compositionally graded thin films including the Si-Fe system obtained in the process of this research became what is greatly useful for future research.
