“…More recently, Veinot and co‐workers demonstrated coupling of organosilanes to hydrogen‐terminated Si nanoparticles catalyzed by the rhodium complex known as Wilkinson's catalyst . Following on the report of non‐catalyzed dehydrogenative coupling of organosilanes to various surfaces including silicon, in this work we find that the reaction proceeds under mild thermal conditions on pSi surfaces without any added catalyst to generate stable, functional coatings, with minimal oxidation, and with retention of the electronic quality of the original Si‐H surface.…”

Organic trihydridosilanes can be grafted to hydrogen-terminated porous Si nanostructures with no catalyst. The reaction proceeds efficiently at 80 8 8C, and it shows little sensitivity to air or water impurities.T he modified surfaces are stable to corrosive aqueous solutions and common organic solvents.O ctadecylsilane H 3 Si(CH 2 ) 17 CH 3 ,a nd functional silanes H 3 Si(CH 2 ) 11 Br,H 3 Si(CH 2 ) 9 CH = CH 2 ,and H 3 Si(CH 2 ) 2 -(CF 2 ) 5 CF 3 are readily grafted. When performed on amesoporous Si wafer,the perfluoro reagent yields asuperhydrophobic surface (contact angle 1518 8). The bromo-derivative is converted to azide,a mine,o ra lkyne functional surfaces via standardt ransformations,a nd the utility of the method is demonstrated by loading of the antibiotic ciprofloxaxin (35 % by mass). When intrinsically photoluminescent porous Si films or nanoparticles are used, photoluminescence is retained in the grafted products,i ndicating that the chemistry does not introduce substantial nonradiative surface traps.

“…The first grafting to silicon substrates as reported by Li et al [72] suffered from several side reactions. The coupling strategy has since been improved by Veinot et al [73] via a Wilkinsson catalyst as well as by Arkles et al [74] and Kim et al [75] that both reported catalyst-free grafting to hydrogen terminated silicon surfaces under mild thermal condition. Kim et al further confirmed stable robust films as well as retention of electronic quality, thus the feasibility of the strategy to functionalize electric devices.…”

As an alternative to standard silicon biofunctionalization protocol based on alkoxysilanes that bind to SiO2 on oxidized silicon substrates, several protocols to form bifunctional interlayers that directly bind to the silicon surface via a strong SiC bond have been developed during the last decades. These interlayers are more stable, and the lack of an insulating layer between the substrate and the interlayer reduces electric noise in biosensor devices. SiC monolayers are not yet regularly applied as the protocols are more complex and generally require an inert gas atmosphere. However, a variety of applications and new methods to form bifunctional SiC interlayers are recently developed. Here, the role these innovative protocols and interlayers play in biofunctionalization of silicon surfaces is reviewed and their applications in electrochemical, microelectromechanical, and optical biosensing are reported. From the analysis of the current situation, it can be concluded that the advantageous properties offered with this approach in many cases more than outweigh the additional processes to form SiC bonded interlayers and the approach is predicted to expand the applications of future silicon‐based biosensors.

Accelerating interest in silicon nitride thin film material system continues in both academic and industrial communities due to its highly desirable physical, chemical, and electrical properties and the potential to enable new device technologies. As considered here, the silicon nitride material system encompasses both non-hydrogenated (SiNx) and hydrogenated (SiNx:H) silicon nitride, as well as silicon nitride-rich films, defined as SiNx with C inclusion, in both non-hydrogenated (SiNx(C)) and hydrogenated (SiNx:H(C)) forms. Due to the extremely high level of interest in these materials, this article is intended as a follow-up to the authors’ earlier publication [A. E. Kaloyeros, F. A. Jové, J. Goff, B. Arkles, Silicon nitride and silicon nitride-rich thin film technologies: trends in deposition techniques and related applications, ECS J. Solid State Sci. Technol., 6, 691 (2017)] that summarized silicon nitride research and development (R&D) trends through the end of 2016. In this survey, emphasis is placed on cutting-edge achievements and innovations from 2017 through 2019 in Si and N source chemistries, vapor phase growth processes, film properties, and emerging applications, particularly in heterodevice areas including sensors, biointerfaces and photonics.
