| Outline of Final Research Achievements |
Hydroxyapatite, Ca10(PO4)6(OH)2 (HA), having weak piezoelectricity is a candidate of novel electronic materials which can solve environmental and finite rare resource problems simultaneously because HA is a bio-ceramics without minor metals. It is the most important factor to control the arrangement of each atom in the HA crystal in order to realize the increase of piezoelectricity. In this study, growth control of the HA thin films with atomically scale was examined by using pulsed laser deposition (PLD) as the first step for the goal of the study. The HA thin films grew with [001] orientation on Al2O3(001) substrate like single crystal. Furthermore, it was achieved to prepare the HA thin films with the proper chemical composition (Ca/P ratio = 10/6 ~ 1.67) by controlling the PLD parameters.
