ci ling panTime-domain terahertz spectroscopy (THz-TDS) provides a non-contact method for characterizing the electrical and dielectric properties of technologically important materials, e.g., transparent and conducting Indium Tin Oxide (ITO) thin films, which are widely used in optoelectronic devices. Recently, ITO nanomaterials have attracted a lot of attention, because of its omidirectional and wideband anti-reflection characteristics. Indium-tin-oxide (ITO) nanorods (NRs) and nanowhiskers (NWhs) were fabricated by an electron-beam glancing-angle deposition (GLAD) system. Two terahertz (THz) time-domain spectrometers (TDS) with combined spectral coverage from 0.15 to 9.00 THz were used. These allow accurate determination of the optical and electrical properties of such ITO nanomaterials in the frequency range from 0.20 to 4.00 THz...

Juan Vivero-Escoto Receives Ralph E. Powe Junior Faculty Award from ORAU

vivero1Chemistry Assistant Professor Juan Vivero-Escoto has received the 2013 Ralph E. Powe Junior Faculty Enhancement Award from Oak Ridge Associate Universities (ORAU), a 109-member university consortium affiliated with Oak Ridge National Laboratory (ORNL). Dr. Vivero-Escoto was among 30 winners in a pool of 147 applicants from the university consortium. Only two faculty members per institution were permitted to apply. Applicants underwent a highly competitive peer-review process organized by ORAU among its members. Dr. Vivero-Escoto’s research interests include the design and synthesis of novel hybrid inorganic-organic materials for biomedical applications. This...

Lets congratulate Princess Mycia Cox, fellow nanoscale PhD student, for defending her Ph.D. dissertation, entitled: "Design and fabrication of low loss and low index optical metamaterials" last week. She completed the work under the supervision of Dr. Michael Fiddy (Electrical and Computer Engineering).



Mycia 22"Meta-materials" is an highly active area of research at UNC Charlotte. The researchers are specially interested in making materials which have their index of refraction close to zero or negative. Mycia's talk  was focused on making and studying these type of low index and preferably low loss materials -particularly at optical frequencies. Its also important that we make these materials through low cost processes   in order to make them in large enough quantities. Given these considerations, nanomaterials especially metallic or semiconductor nanocrystals fit the criteria .In mycia's case ,she fabricated and studied aluminium doped zinc-oxide nanoparticles. Her work was also supplemented by extensive simulations  and modeling. A large number of students including fellow nano students and...

Nanoscale Science - Faculty in Focus

Research in our group focuses on the design, and synthesis of novel hybrid inorganic-organic materials for a wide variety of applications, predominantly in biomedicine, renewable energy, and catalysis. Our approach is multidisciplinary, interfacing chemistry, biology, and material science. By its very nature our research will provide an excellent training environment for undergraduates, graduate students and postdoctoral research fellows.
