AB The aim of this work is to present a physical method of Ti nanocolumn fabrication on glass substrates, referred to as glancing angle deposition (GLAD). For precise and controllable evaporation, an electron beam evaporation system has been used. Scanning electron microscope micrographs from plan and cross section samples confirmed the fabrication of Ti nanocolumns. In addition, we have studied the photoconductivity (PC) of Ti nanocolumns. We have measured the PC time response for three voltages: 0, 1, and 2 V. Our results in all voltages show that there is similar behavior for time response. Meanwhile, there are two slopes for the PC time response in each external bias voltage. Also, our PC measurement showed that the PC current decreases with enhancement of the tilt angle in each voltage. The results are quite different compared with bulk Ti and confirm that Ti nanocolumns have different properties with respect to the bulk samples.
