This invention provides a method for fabricating a lateral dual-electrode device array based on laser etching. Utilizing the cumulative photothermal effect of pulsed laser during the etching process, an insulating channel is formed by etching a conductive layer with the pulsed laser. Simultaneously, the photothermal effect generated near the pulsed laser beam destroys the hydrophobic layer on both sides of the channel, thereby reducing its hydrophobic effect and forming a heat-affected zone (HAZ). When a solution capable of growing crystals using a solution method is coated onto the substrate, the presence of the HAZ ensures that the solution can wet and completely cover the laser-etched channel. Finally, the deposited crystalline film can laterally span both sides of the channel, forming a lateral dual-electrode device. According to the fabrication method of this invention, there is no need to separately prepare the array of active and electrode materials; only a single patterning process, laser etching, is required to complete the fabrication, achieving the fabrication of large-area, high-throughput, arrayed lateral dual-electrode devices.
