چکیده: Dielectrophoretic alignment of the Selenium

(Se) nanorods is reported for electrical characterization and

possible applications as micro/nano devices. Selenium

nanorods were successfully synthesized using a reverse

microemulsion process. The produced material was

investigated structurally using X-ray diffraction and

transmission electron microscope. Suspensions of the Se

powder in the concentration of 0.1 (g/l) were prepared in

pure ethanol. Interdigitated platinum electrodes were

employed for manipulation of suspended materials in the

fluid. When Se particles were exposed to the platinum

electrodes in two frequencies of 10 and 100 kHz, dielectrophoretic

force captured suspended particles onto the

interdigitated micro-electrode array. The trapped Se

nanorods were aligned along the electric field lines and

bridged the electrode gaps. Dielectrophoretic entrapment of

Se nanorods on microelectrode was also detected by

impedance measurements. The device was characterized

and can potentially be used as a nanodevice.
