AB  - We investigate carrier transport properties of silicon nanowire (SiNW) arrays decorated with TiO2nanoparticles (NPs). Ohmic conduction was dominant at lower voltages and space charge limitedcurrent with and without traps was observed at higher voltages. Mott’s 3D variable range hopingmechanism was found to be dominant at lower temperatures. The minimum hopping distance(Rmin) for n and p-SiNWs/TiO2 NPs devices was 1.5 nm and 0.68 nm, respectively, at 77 K. Thedecrease in the value of Rmin can be attributed to higher carrier mobility in p-SiNWs/TiO2 NPs thanthat of n-SiNWs/TiO2 NPs hybrid device.
