| Abstract Scope |
The excitonic and multibody interactions in some semiconducting two-dimensional (2D) crystallites, their strain-dependent properties and pristine atomically flat interfaces, coupled with the ability to solution-process these materials, offer a rich playground to unveil fundamental physical mechanisms for exciting and innovative devices. Amongst these, the transition metal dichalcogenides (TMDCs), such as tungsten diselenide (WSe2) and niobium diselenide (NbSe2) are finding promise in nanoelectronics, optoelectronics, sensors and quantum photonics. In this work, we have analysed the light-matter interactions in superconducting NbSe2 and semiconducting WSe2 toward sensing devices enabled by quantum phenomena. Moreover, solution-processed 2D materials, including lower dimensionality perovskites, have provided a pathway to realize a rich plethora of flexible and bendable sensing devices which will also be discussed. |
