Two dimensional materials for on-chip photonics

2D material

Optoelectronic applications such as photodetectors and emitters rely on the ability of its active material to interact strongly with light and one could not be blamed for questioning the ability of two dimensional (2D) materials here. After all, its cross-section is made up of at most few atoms which means there is hardly enough matter …

Imaginenano 2018 : Graphene for Industry Conference

Imaginenano 2018

There has been a slow but steady progress in the technology readiness levels of graphene and related 2D materials based applications. While there is still a significant amount of fundamental research taking place across the globe, there certainly are some early signs of scaled up development of materials, devices and associated fabrication processes. This was …
