Abstract: In this study, we applied Density Functional Theory (DFT) and Nonequilibrium Green’s Function (NEGF) framework to investigate the quantum transport characteristics of Zigzag Blue Phosphorene (ZblueP) nanoribbons doped with Silicon (Si). We aimed to delve into the structural stability, as well as the electronic and transport properties of the device in question. Intriguingly, we discovered that doping strategies can effectively morph a monolayer (ML) of Si-doped ZblueP into a spintronic nanodevice boasting several distinctive transport attributes. Firstly, under certain bias, our model displayed an impressively high dual spin filtering effect (SFE). Secondly, we observed a spin rectifier with a considerable rectifica-tion ratio (RR) of 8.50 x 102. Lastly, we noticed negative differential resistance featuring a peak-to-valley current ratio (PVCR) of 9.65 x 102. Our findings suggest a promising path towards the advancement of high-performing ML ZblueP spintronics technology through Si doping. The results underscore that our model holds substantial potential for utilization in nanoscale spintronic devices.
