Acquiring real-time spectral information in point-of-care diagnosis, internet-of-things, and other lab-on-chip applications requires spectrometers with hetero-integration capability and miniaturized features. Compared to conventional semiconductors integrated by heteroepitaxy, solution-processable semiconductors provide a much-flexible integration platform due to their solution-processability, and therefore, are more suitable for the multi-material integrated system. However, solution-processable semiconductors are usually incompatible with micro-fabrication processes, making them far from practical use in various lab-on-chip applications.
