“…In the current era of nanoscience and nanotechnology, low-dimensional materials, especially semiconductors, have attracted much attention because of their technologically important tunable electronic [5,6] and opto-electronic properties, delivering promising potentials in many fields such as energy storage, [7][8][9][10][11] conversion, [12] and sensors, [13][14][15][16][17] in comparison with their bulk counterparts and have gained enormous attention from researchers. In particular, silicon (Si) nanostructures (NSs), including porous Si, [18][19][20][21][22][23][24][25] Si nanowires (SiNWs), and fractal porous SiNWs, are of special interest as they exhibit superior opto-electronic properties with improved device performance, such as narrower spectral line width, low threshold current densities, [26] and reduced temperature sensitivity.…”
