Project description
Alternative-to-epitaxy manufacturing method holds promise for high-performance optoelectronic devices
Low-cost optoelectronic devices emitting in the short-wave infrared part of the electromagnetic spectrum are used in a range of applications. These include 3D weather imaging, night vision car safety and security cameras, chemical hazard detection, environmental sensing and biomedical diagnostics. Manufacturers currently grow such devices on epitaxial III-V semiconductors. The EU-funded ECOSWIR project will use a solution-processed technology based on colloidal quantum dots (CQDs). Unlike epitaxial growth, the proposed technology is lower-cost and compatible with CMOS processes. The newly developed optoelectronic devices will be grown on indium antimonide, a III-V semiconductor which owing to its high carrier mobility in room temperature and small exciton energy is expected to lead to unprecedented device performances.
Objective
The development of low-cost optoelectronic devices in the short-wave infrared (SWIR, 1-2 um), would open up a huge number of applications, such as 3D and adverse weather imaging, night vision for surveillance and automotive safety, chemical hazard detection, environmental sensing, and biomedical diagnostics etc. leading to a direct and huge impact on quality of life, health, and security, provided that such technologies are available at low cost and high volumes, to serve consumer electronics markets. To address this large consumer market volume the necessity for low-cost, non-toxic, and complementary metal oxide semiconductor (CMOS) compatible SWIR photodetectors is therefore indispensable. To date, the SWIR has been served by costly epitaxial III-V semiconductors, which are not monolithically integrated to silicon (CMOS) electronics, and suffer from high growth cost and low volume manufacturing. Compared to epitaxial technology, solution-processed technology based on colloidal quantum dots (CQDs) is more promising for SWIR photodetectors due to low cost and high volume manufacturing, and their CMOS integrability. On the other hand, InSb is an environmentally friendly III–V semiconductor which possesses a narrow direct band gap and the highest room temperature carrier mobility, and the smallest exciton binding energy of all semiconductors, thus being ideal for SWIR photodetectors. Therefore, ECOSWIR aims to develop a whole new material platform based on non-epitaxial InSb CQDs that, in contrast to current III-V technologies, will enable CMOS compatibility and large-scale production of optoelectronic materials.Utilizing this achievement, ECOSWIR will provide a proof of principle of InSb CQDs SWIR photodetectors with performance that cannot be met by any prior CQDs devices, that will be competitive to the costly epitaxial technology and warrant introduction into high-volume, consumer electronics markets and pave the way towards printable SWIR photodetctors.
