“…), which play a crucial role for the effective detection of (bio)molecules. Mainly, MOx nanolayers/nanoparticles can be deposited over a nano-Si surface through the following techniques: (i) RF and DC magnetron sputtering [24,34,36,37,120,121,123,124,125,126]; (ii) sol–gel/hydrothermal synthesis + spin coating [17,26,127,128,129,130,131]; (iii) drop casting technique + pulsed laser ablation in liquid [132]; (iv) vapor–liquid–solid growth and chemical vapor deposition [25,40,133]; (v) catalytic immersion method [134]; and (vi) electrochemical and chemical deposition [35,122,135].…”

“…It has been established that Au, Ag, Pd, and Pt nanoparticles deposited over silicon nanopillars or nanowires can be aggregated to “hot spots” and demonstrate a high enhancement factor in SERS-based biosensors with a detection limit less than 10 -12 M [33]. Furthermore, SiNWs and SiNPs in conjunction with metal oxides (TiO 2 , ZnO, WO 3 , F 2 O 3 , TeO 2 ) have shown promising results for gas and biomolecule detection via an electrochemical response with a detection limit of about 1 ppm [34,35,36,37,38]. Recently, a number of new composites have been developed based on SiNWs and SiNPs with sulfides (CdS, MoS 2 ) [39,40] and nitrides (Si 3 N 4 ) [41] that are suitable for sensitive light, humidity, and gas detection due to enhanced absorption and adsorption.…”

“…Зокрема, це стосується поруватих напівпровідників [9], поверхня і об'єм яких пронизані по-рами, що можуть слугувати пасткою для йонів газів або променів світла визначеної довжини. Поруваті напівпровідники знайшли широке застосування і як буферні шари для створення на основі напівпровідників нітридів [10]. Ó цьому випадку поруватий шар являє собою м'яку підкладинку, що уможливлює мінімізувати напруження, які виникають між ґратницями напівпровідникового кристалу та нітриду [11].…”
