TLDR
A major problem with the Si-based MEMS technology is that Si has poor mechanical and tribological properties as discussed by the authors, which makes it unsuitable for MEMS devices, and therefore it is not suitable for them.About:

TL;DR: It is shown that hardening of cBN is continuous with decreasing twin thickness down to the smallest sizes investigated, contrasting with the expected reverse Hall–Petch effect below a critical grain size or the twin thickness of ∼10–15 nm found in metals and alloys.

Vapor growth of diamond on diamond and other surfaces
TL;DR: In this article, the growth rate of homoepitaxial diamond films reached 1 μm/h at 1000°C; film properties were identical to those of bulk crystals.
Journal ArticleDOI
Fullerenes as precursors for diamond film growth without hydrogen or oxygen additions
TL;DR: In this article, the growth of diamond films using fullerene precursors in an argon microwave plasma was reported, a unique development achieved without the addition of hydrogen or oxygen, and it was speculated that collisional fragmentation of C60 to give C2 could be responsible for the high growth rate of the very fine-grained diamond films.
