“…In principle, the well-defined preparation of a sample is useful for any (surface science) characterization method. It is thus not surprising that pMS was successfully used in combination with many other surface analysis methods such as secondary ionization mass spectrometry (63,135), infrared spectroscopy (96), Raman spectroscopy (64,136), and electrochemistry (92).…”

“…However, these sources will be developed only if applications are in sight. Functional coatings fabricated by pMS have been demonstrated (74,139), and IBD can be used to fabricate device surfaces under conditions accessible only to hyperthermal ion beams (36,64).…”

“…Both effects offer completely new possibilities for epitaxy: Surface-induced dissociation could be used to generate reactive species away from thermal equilibrium without heating that can undergo reactions that are otherwise not conceivable (89). A few examples demonstrate this possibility of covalent surface modification (64,(90)(91)(92). Whereas the energy dependence of the structure and the morphology of defects created by atomic ion impacts have been studied in depth (93,94), little is known about the structures formed by energetic collisions of molecules because so far no high-resolution imaging has been performed.…”

Measuring and understanding the complexity that arises when nanostructures interact with their environment are one of the major current challenges of nanoscale science and technology. High-resolution microscopy methods such as scanning probe microscopy have the capacity to investigate nanoscale systems with ultimate precision, for which, however, atomic scale precise preparation methods of surface science are a necessity. Preparative mass spectrometry (pMS), defined as the controlled deposition of m/z filtered ion beams, with soft ionization sources links the world of large, biological molecules and surface science, enabling atomic scale chemical control of molecular deposition in ultrahigh vacuum (UHV). Here we explore the application of high-resolution scanning probe microscopy and spectroscopy to the characterization of structure and properties of large molecules. We introduce the fundamental principles of the combined experiments electrospray ion beam deposition and scanning tunneling microscopy. Examples for the deposition and investigation of single particles, for layer and film growth, and for the investigation of electronic properties of individual nonvolatile molecules show that state-of-the-art pMS technology provides a platform analog to thermal evaporation in conventional molecular beam epitaxy. Additionally, it offers additional, unique features due to the use of charged polyatomic particles. This new field is an enormous sandbox for novel molecular materials research and demands the development of advanced molecular ion beam technology.

“…Chemical functionalization routes are being widely pursued to extend the spectrum of attainable properties of graphene, such as bandgap opening . A repertoire of methods has been reported, the majority of which are based on thermally activated chemistry in the gas or liquid phase –. Photochemical methods have also been investigated, although they are quite rare .…”

We present a contactless strategy based on bipolar electrochemistry for the local chemical modification of monolayer graphene sheets supported on a substrate. Specifically, peripheral graphene regions are directly modified by copper nanoparticles, the characteristics of which are controllable through the bipolar deposition parameters. This functionalization route provides access to hybrid monolayer graphene modified, for example, with two different metals on opposing peripheries. The presented strategy constitutes a new way to functionalize graphene and an avenue for systematically studying bipolar electrochemistry at the nanoscale.

“…However, the absence of a bandgap has impeded the applications of graphene in nanoelectroncis. To overcome the disadvantages caused by the gapless band in graphene, intensive efforts have been strived, such as chemical doping, topography control, etc 19, 20, 21. Unfortunately, only very limited success has been achieved 20, 22, 23, 24.…”

View full text Add to dashboard Cite

As an important component of 2D layered materials (2DLMs), the 2D group IV metal chalcogenides (GIVMCs) have drawn much attention recently due to their earth‐abundant, low‐cost, and environmentally friendly characteristics, thus catering well to the sustainable electronics and optoelectronics applications. In this instructive review, the booming research advancements of 2D GIVMCs in the last few years have been presented. First, the unique crystal and electronic structures are introduced, suggesting novel physical properties. Then the various methods adopted for synthesis of 2D GIVMCs are summarized such as mechanical exfoliation, solvothermal method, and vapor deposition. Furthermore, the review focuses on the applications in field effect transistors and photodetectors based on 2D GIVMCs, and extends to flexible devices. Additionally, the 2D GIVMCs based ternary alloys and heterostructures have also been presented, as well as the applications in electronics and optoelectronics. Finally, the conclusion and outlook have also been presented in the end of the review.
