High aspect ratio GeO_2 nano- and microwires with waveguiding behaviour Hidalgo Alcalde, Pedro Méndez Martín, María Bianchi Piqueras De Noriega, Francisco Javier © 2007 IOP Publishing Ltd. This work has been supported by MEC (Project MAT2003-00455) and UCM-CM (Group 910146). High aspect ratio GeO_2 nano- and microwires have been grown by thermal treatment at 600 degrees C of compacted Ge powder under argon flow. The wires have cross-sectional dimensions from less than 100 nm to about 1 mu m, depending on the duration of the treatment, and lengths of up to about 2000 mu m. Waveguide behaviour of the wires was demonstrated for visible light, which shows the potential applications of these structures for optical nanodevices. 2023-06-20T10:39:58Z 2023-06-20T10:39:58Z 2007-04-18 journal article 0957-4484 10.1088/0957-4484/18/15/155203 https://hdl.handle.net/20.500.14352/50943 http://iopscience.iop.org/0957-4484/18/15/155203 http://iopscience.iop.org eng MAT 2003-00455 Group 910146 open access Iop Publishing Ltd
