In this study, we evaluated a physical reservoir computing (RC) device based on molybdenum diselenide with a nanoflower structure (MoSe₂ NF). The MoSe₂ NF was deposited alone on a Si substrate, and I-V characteristics were measured across multiple electrodes. The results revealed strong nonlinearity and the presence of high-order harmonic components. In a waveform generation task, signals obtained from all output electrodes enabled accurate waveform reconstruction, and the evaluation of short-term memory capacity also demonstrated favorable retention performance. These findings suggest that MoSe₂ NF is a highly promising material for high-performance RC devices.
