The growth of Zn2SnO4 nanorods on two differently prepared ZnO seed layers is demonstrated using a hydrothermal approach. are dip-coating and electrodeposition techniques. grown in the cubic phase. However, different result alternation diameter nanorods. photocurrent an electrodeposited layer ∼4.5 times larger than that dip-coated layer. Nyquist plots lower charge transfer resistance (Rct = 37.7 Ω) bulk (Rbulk 64 kΩ), improving transport properties. change significantly alters behavior. calculated injection efficiency did not exhibit significant change. there was 1.6-fold enhancement observed separation for when
