TL;DR: The Si/MoS2 heterojunction is found to be sensitive to broadband wavelengths ranging from visible to near-infrared light with maximum detectivity up to ≈1.4 × 1012 Jones (2 V bias).

TL;DR: In this article, the photocurrent spectra of the nanowire heterojunctions have been investigated at room temperature to study the spectral responsivity and detectivity of the core-shell nanowires.

TL;DR: In this article, a drain current model for triple-gate n-type junctionless nanowire transistors is proposed based on the solution of the Poisson equation, which is validated using 3-D TCAD simulations where the drain current and its derivatives, the potential, and the charge density have been compared, showing a good agreement for all parameters.

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.

TL;DR: In this article, the effective electron mobility in long-channel silicon-on-insulator junctionless multigate metal-oxide-semiconductor transistors is experimentally studied and it is found that the mobility in heavily doped narrow nanowire (NW) devices at low to moderately high carrier densities significantly exceeds that in wide (planar) devices with the same silicon thickness and doping.
