Wafer-Scale Synthesized MoS2/Porous Silicon Nanostructures for Efficient and Selective Ethanol Sensing at Room Temperature
TL;DR: This paper presents the performance of a highly selective ethanol sensor based on MoS2-functionalized porous silicon (PSi), and an enhancement in sensitivity and a selective response for ethanol were observed, with a minimum detection limit of 1 ppm.
Journal ArticleDOI
Scalable fabrication of prototype sensor for selective and sub-ppm level ethanol sensing based on TiO2 nanotubes decorated porous silicon
TL;DR: In this paper, a miniaturized prototype sensor based on TiO2 nanotubes/porous silicon (PS) heterojunction is developed for selective ethanol sensing in sub-ppm range.
Journal ArticleDOI
Synthesis of α-MoO3 nano-flakes by dry oxidation of RF sputtered Mo thin films and their application in gas sensing
TL;DR: In this article, the synthesis of orthorhombic (α) MoO3 nano-flakes by dry oxidation of RF sputtered Mo thin film is presented, where the influence of Mo thickness variation, oxidation temperature and time on the crystallographic structure, surface morphology and roughness of MoO 3 thin films was studied using SEM, AFM, XRD and Raman spectroscopy.
Journal ArticleDOI
Effect of TiO2 Functionalization on Nano-Porous Silicon for Selective Alcohol Sensing at Room Temperature
TL;DR: In this paper, a room temperature operated sensor for detection of alcohol vapours in low ppm range based on TiO 2 functionalized nano-porous silicon (PSi) is demonstrated.
Journal ArticleDOI
High performance broadband photodetector based on MoS2/porous silicon heterojunction
TL;DR: In this paper, a high speed efficient broadband photodetector based on a vertical n-MoS2/p-porous silicon heterostructure has been demonstrated, with a maximum responsivity of 9'A/W (550-850'nm) with a very high detectivity of ∼1014 Jones.
