High aspect ratio GeO_2 nano- and microwires with waveguiding behaviour Hidalgo Alcalde, Pedro Méndez Martín, María Bianchi Piqueras De Noriega, Francisco Javier 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 2023-06-20T10:39:58Z 2007-04-18 journal article https://hdl.handle.net/20.500.14352/50943 0957-4484 10.1088/0957-4484/18/15/155203 eng MAT 2003-00455 Group 910146 open access Iop Publishing Ltd
