| Summary: | In this thesis, ZnO and ZnO-based semiconductor materials were fabricated by
pulsed laser deposition (PLD) and chemical vapor deposition (CVD) methods. The
optical and crystal properties of ZnO and ZnO-based semiconductor materials with and
without surface plasmon (SP) effect were characterized by various techniques. This thesis
focuses in two main aspects: (1) First part is the crystal and optical study of ZnO thin film,
ZnCdO alloy and ZnCdO/ZnO single quantum well (QW). (2) Second part is the study of
SP effect on ZnO and ZnO-based semiconductor materials. Among all the potential uses
of these materials, light emitting device is one of the important applications. Thus,
improving the emission efficiency of ZnO and ZnO-based semiconductors will be critical.
SP effect has been certified as an effective way to enhance the emission efficiency of
many semiconductor materials. So the study of the SP effect on the ZnO and ZnO-based
materials will be very useful for ZnO-based light emitting devices. |
