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.
半导体材料是高性能电子产品发展的核心，这些电子产品能够在浸入水溶液、地下水或生物流体中完全溶解，可应用于临时生物医学植入物、环境可降解传感器和其他系统。这里报道的结果包括对多晶硅、非晶硅、硅锗和锗在不同 pH 值和温度的水溶液中水解溶解的综合研究。体外细胞毒性评估证明了材料及其溶解终产物的生物相容性，从而支持它们在可生物降解电子产品中的应用潜力。一个完全可溶解的薄膜太阳能电池说明了将这些半导体集成到功能系统中的能力。
