Growth and optical properties of phosphorus-doped ZnO nanowires ContentsIntroductionExperimentalResults and discussionConclusionsIntroduction ZnO nanowires have attracted increasing interest due to its potential applications in electronics and optoelectronicsp-type doping of ZnO has a high concentration of nitrogen and a low-defect density We demonstrate a versatile growth technique to synthesize phosphorus-doped ZnO (ZnO:P) nanowires ina reproducible wayExperimentalZnO:P nanowires are synthesized via a vapor transport process based on a single source precursor, Zn3P2The temperat

ZnO와 결합한 것 을 알 수있다 그리고 Sn도핑 ZnO는 어닐링에 대한 효과가 나타났다. 1. Introduction ZnO is an important wide-band-gap semiconductor that has a direct band-gap (3.37 eV) with a high exciton binding energy (60 meV), which is greater than the thermal energy at room temperature.  Impurity-doping in semiconductors with selective elements greatly affects the basic physical properties, such as the electrical, optical, and magnetic properties, which are crucial for their practical application. Many groups have reported the synthesis of doped ZnO nanoparti

Study of structural and optical properties of Ge doped ZnO filmscontentsIntroductionExperimentsResult and discussionConclusionsIntroductionGe is an indirect band gap semiconductor with smaller energy difference between indirect gap and direct gap, and smaller effective masses for electron and hole pairs.Small ionic radius difference between Ge ion and Zn ion.These characteristics lead to the expectation that it is much easier to change the electronic structure around the band edge.ExperimentsA sintered ceramic ZnO target, the surface of which was covered with 3 small area Ge slices
