Flexible electronic devices, fabricated on bendable and light-weight substrates, have gained significant attention in recent years. While devices made with low-temperature processed materials such as polymers/plastics have found application in flexible electronics, high-temperature processed inorganic semiconductors with substantially higher opto-electronic properties are yet to make their mark in this marketspace. Here, we provide an overview of the progress made in the development of epitaxial single-crystalline-like semiconductors (silicon, germanium, III-Vs) on low-cost flexible substrates (metal foils, glass, ceramics) by roll-to-roll (R2R) chemical vapor deposition processes conducted at elevated temperatures. The single-crystalline-like films exhibit high carrier-mobility and optical properties, nearly comparable to wafer counterparts. Flexible IIIV single-junction solar cells, Si and Ge thin film transistors and III-V field effect transistors will be discussed. The ability to grow high-quality single-crystalline-like materials by R2R processing on alternate flexible substrates may open new opportunities in scalable manufacturing of low-cost, high-performance and large-area flexible electronic devices.
