Terminal acylacetylenes act as trimodal auxiliaries in SHN cross-coupling of pyridines with phosphine chalcogenides. The reaction proceeds via phosphorylation of the pyridine 2 position followed by 2 → 4-migration of phosphoryl moieties.

ABSTRACTTwo-dimensional layered materials, materials with weak out-of-plane van der Waals bonding and strong in-plane covalent bonding, have attracted special attention in recent years since the isolation and characterization of monolayer graphite, the graphene. The electrical bandgap in Transition Metal Di-Chalcogenides (TMDCs), non-existent in graphene, make them a good alternative family of materials for novel electronic and optoelectronic applications. 2H- MoS2, one of the most stable TMDCs, has been extensively studied, including the synthesis methods, and its potential applications in photodetection. The chemical vapor deposition (CVD) synthesis method has increased its potential over the years. The advantages of this method are scalability compared to micromechanical exfoliation, common process used in research laboratories, and the maintenance of the quality and intrinsic properties of the material compared to the liquid exfoliation methods. In this work, we synthesized high quality pristine 2H-MoS2 via atmospheric pressure chemical vapor deposition (APCVD) by vapor phase reaction of MoO3 and S powder precursors. The samples were characterized via Raman and photoluminescence (PL) spectroscopy and compared to mechanically exfoliated MoS2 crystal by measuring the full-width half maxima (FWHM) of monolayer and few-layer mesoscopic flakes. In addition, the CVD synthesized single and few-layered MoS2 domains were transferred to different substrates using a high yield process, including a flexible substrate, preserving the quality of the material. Finally, and mechanically exfoliated MoS2 two-terminal photodetector was designed, fabricated, and measured. Demonstrating thus the capability of heterostructure fabrication and the quality of our synthesis and device fabrication process.

Thermal cycling of chalcogenide materials (Ge2Sb2Te5 or GeSb for example) causes switching between two electrical resistance levels in the materials. This is the basis of PC memory, and offers the possibility of use for programmable signal switching in electronic systems as well. Here we propose a design for connection topology, using dual tip AFM-type probes. The design subdivides a single phase change via into a parallel array of three-terminal sub-vias which are well-suited to addressing with probes. This sub-division reduces required power and current to acceptable levels. Experimental inputs to the model were extracted from two sources. First, current levels were limited to levels that have previously been shown possible to deliver with AFM tips. Secondly, measurements of PC resistance as a function of cooling time were used to determine required heat sinking of the sub-via structures.
