We demonstrated a resistive switching Pt/InGaZnO/Al memory device based on an arc-shaped bottom electrode (BE), which was fabricated by using a polystyrene (PS) nanosphere template. For the device without an arc-shaped BE, netlike conducting filaments (CFs) are easily formed, resulting in an incomplete rupture and a large resistance fluctuation. In comparison, the electric field direction would point to the center of the arc, instead of being vertical to the planar electrode. Therefore, the CFs prefer to form a simple, radial structure around the arc-shaped BE, and the simplified CFs are effective for achieving a narrower resistance distribution and RS improvement.
