1：Experimental Design and Method Selection:

The study involves fabricating two types of devices: 2D-NPSANs (monolayer of AzBT-functionalized Au NPs) and cluster-NPSANs (multilayer networks). Electrical conductance measurements are performed under light illumination at specific wavelengths (365 nm, 470 nm, 590 nm) to induce isomerization. The methodology includes pre-configuring molecules in trans or cis states, followed by plasmonic excitation and current monitoring.

2：Sample Selection and Data Sources:

Samples consist of gold nanoparticles (10 nm diameter) functionalized with AzBT molecules, synthesized via ligand exchange. Devices are fabricated on silicon substrates with coplanar Ti/Au electrodes using electron-beam lithography.

3：List of Experimental Equipment and Materials:

Equipment includes an Agilent 4156C semiconductor parameter analyzer, Suss Microtec PM-5 probe station, MBRAUN glove box, Thorlabs LEDs (365 nm, 470 nm, 590 nm), and Thorlabs PM200 optical power meter. Materials include AzBT molecules, citrate-capped Au NPs, and solvents like TCE and hexane.

4：Experimental Procedures and Operational Workflow:

Devices are pre-configured by illumination at 365 nm or 470 nm for 1-1.5 hours, followed by dark periods. Then, plasmonic excitation at 590 nm is applied, and current vs. time is recorded at a constant bias of 2.5 V. UV-visible isomerization kinetics are also measured for comparison.

5：5 hours, followed by dark periods. Then, plasmonic excitation at 590 nm is applied, and current vs. time is recorded at a constant bias of 5 V. UV-visible isomerization kinetics are also measured for comparison. Data Analysis Methods:

5. Data Analysis Methods: Data analysis involves exponential fitting of current-time curves to extract time constants, correction for drift, and comparison of conductance changes. Theoretical models like Tien-Gordon for plasmon-assisted tunneling are considered but dismissed based on calculations.
