Dissolution Chemistry and Biocompatibility of Silicon- and Germanium-Based Semiconductors for Transient Electronics
Semiconducting
materials are central to the development of high-performance electronics
that are capable of dissolving completely when immersed in aqueous
solutions, groundwater, or biofluids, for applications in temporary
biomedical implants, environmentally degradable sensors, and other
systems. The results reported here include comprehensive studies of
the dissolution by hydrolysis of polycrystalline silicon, amorphous
silicon, silicon–germanium, and germanium in aqueous solutions
of various pH values and temperatures. In vitro cellular toxicity
evaluations demonstrate the biocompatibility of the materials and
end products of dissolution, thereby supporting their potential for
use in biodegradable electronics. A fully dissolvable thin-film solar
cell illustrates the ability to integrate these semiconductors into
functional systems
