Observation of the photovoltaic effect in a van der Waals heterostructure

Abstract

Van der Waals (vdW) heterostructures, which can be assembled with various two-dimensional materials, provide a versatile platform for exploring emergent phenomena. Here we report an observation of the photovoltaic effect...

Large area van der Waals MoS2–WS2 heterostructures for visible-light energy conversion

“…61 and in more recent references. 27,[62][63][64][65][66][67][68] We also stress that the absolute photocurrent and photovoltage values which have been measured in our proofof-concept TMD heterojunction are far too low for any realistic electro-optical photoconversion application. This limitation is primarily due to the very high series resistance of the graphene bilayer back contact, in the range of 20 kΩ (more details in ESI † section S4).…”

Insulating 6,6‐Phenyl‐C61‐butyric Acid Methyl Ester on Transition‐Metal Dichalcogenides: Impact of the Hybrid Materials on the Optical and Electrical Properties

“…Furthermore, 0D‐materials have sizes that are several orders of magnitude lower than the resolution of visible light, rendering this approach inapplicable. The main objective of transfer procedures is to obtain ultraclean samples to thoroughly investigate any property such as interlayer excitons, [14] the photovoltaic effect [17,18] or develop new nanodevices [19,20] . Nanomaterials mixed in liquid or solid state have the risk to produce random aggregated species, poisoning or directly killing their low dimensional properties; nevertheless, based in its simplicity and high‐yield, this approach can easily reach real applications [21] .…”

Electrical properties and band alignments of Sb2Te3/Si heterojunctions, low-barrier Sb2Te3/n-Si and high-barrier Sb2Te3/p-Si junctions

“…Prominent examples of such materials include transitionmetal dichalcogenides, transition-metal oxides, and pnictogen chalcogenides. [10][11][12][13][14][15] Consequently, the development of heterostructures utilizing vdW layered materials has gained substantial attention in recent research.…”
