Monodispersed Bi-Tenano arrays are achieved via template-free bipotentiostatic\ndeposition. The diameter and length of individual nanorod is ~80 nm\nand ~250 nm respectively. The electrodeposition process is demonstrated to\nfollow a two-step mechanism: an instantaneous reductive potential is applied\nto form dispersive nuclei, then a reversal oxidative potential strips partial Bi\natoms to prevent further cross-growth. Repeatedly, the nano arrays film is\nobtained eventually. The thermoelectric properties of the obtained Bi-Tenano\narrays such as electrical resistance, carrier density, Seebeck coefficient and\npower factor are measured to be 2.438 Ã?â?? 10âË?â??4 Ã?©Ã?·m, 4.251 Ã?â?? 1020 cmâË?â??3, âË?â??25.892\nÃ?¼VÃ?·KâË?â??1, 2.750 Ã?â?? 10âË?â??6 WÃ?·mâË?â??1Ã?·K2, respectively.
