Considerations for Neuromorphic Supercomputing in Semiconducting and Superconducting Optoelectronic Hardware
By Technical Paper Link - 18 Nov, 2021 - Comments: 0

Abstract: "Any large-scale spiking neuromorphic system striving for complexity at the level of the human brain and beyond will need to be co-optimized for communication and computation. Such reasoning leads to the proposal for optoelectronic neuromorphic platforms that leverage the complementary properties of optics and electronics. Starting from the conjecture that future large-scale neurom... » read more

Substitutional synthesis of sub-nanometer InGaN/GaN quantum wells with high indium content
By Technical Paper Link - 03 Nov, 2021 - Comments: 0

Abstract "InGaN/GaN quantum wells (QWs) with sub-nanometer thickness can be employed in short-period superlattices for bandgap engineering of efficient optoelectronic devices, as well as for exploiting topological insulator behavior in III-nitride semiconductors. However, it had been argued that the highest indium content in such ultra-thin QWs is kinetically limited to a maximum of 33%, narro... » read more
