Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

Advanced Electronic Materials
The integration of silver nanowire (AgNW) networks with MoS2/ZnO heterojunctions leads to a remarkable enhancement in surface photovoltage (SPV) response. In the visible wavelength range, the heterojunctions with AgNWs achieve an SPV signal of ≈200 mV, a
