Using the methods of SEM and Spectro-radiometer, we analyzed the optical properties of the textured AZO thin films. We confirmed that the vacuum ambient post-annealing process is effective method for increasing the efficiency of long wavelength LED.

This new paradigm of information technology can be well served by advances in bio-nano electronics. By way of presenting specific examples, this short course introduces a few basic concepts, methods and recent advances on three fronts of bio-nano electronics: (a) DNA directed self-assembly and growth of nanostructures (b) Real-time, scalable, reconfigurable, and direct read-out of bio-molecular signals (by nanoelectronic circuitry via programmable DNA wiring and addressing) (c) Intracellular probing, delivery, and exploration by nano-electrodes.","PeriodicalId":200163,"journal":{"name":"2006 IEEE Nanotechnology Materials and Devices Conference","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116754844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, nanomaterials like carbon nanotube, metal nanoparticle and quantum dots contribute to improve performance of biosensors and biochips. The application of nanotechnology in biomedical sciences will provide information with unprecedented precision and sensitivity, which will not only provide much deeper understanding of biosystems but also lead to the development of new revolutionary modalities of biomolecular manufacturing, early diagnostics, medical treatment, and disease prevention beyond the cellular level to that of DNA and individual proteins, the building blocks of the life process.
