Nanomaterials and Radiation Absorbers
Emberion’s knowhow of integrating optically absorbing materials with graphene transducers provides a versatile way of creating sensors and detectors on CMOS ROIC substrates for diverse applications. Emberion has optimised various processes and has developed device sensor structures using nanomaterials such as colloidal quantum dots and graphene.
Colloidal quantum dot image sensors diverge from conventional image sensors:
- Colloidal quantum dot (CQD) devices are produced using wet chemistry, which make their processing inexpensive and highly scalable.
- Their wavelength range of photon absorption can be tuned and be made very broad.
- Even the quantum efficiency of CQD devices is typically lower, the low noise of the CQD photodiodes compensates it and the noise equivalent power (NEP) is sufficient for most of the applications.
- CQD SWIR image sensors can be operated at higher temperatures, reducing the system and sensor packaging cost.
- Based on possible direct monolithic integration on CMOS wafers, CQD pixels are scalable to small pixel size and high image resolution formats, e.g., up to 4K HD format.
- Emberion can scale its pixel arrays either down to very small pixel sizes or larger sizes depending on the application needs.
