New paper published reporting results of the EspLORE project. The formation of  carbon atomic wires in liquid has been investigated in situ by Raman spectroscopy (i.e. SERS) during the laser ablation process. In situ surface-enhanced Raman spectroscopy to investigate polyyne formation during pulsed laser ablation in liquid P.Marabotti, S.Peggiani, A.Facibeni, P.Serafini, A.Milani, V.Russo, A.Li Bassi, C.S.Casari Carbon 189, 219-229 (2022)

We investigated how the properties of graphdiynes (2D carbon crystals) depend on the topology of sp and sp2 carbon connections. By a theoretical work we have outlined the role of the structure of molecular fragments in the final properties of extended sp-sp2 carbon crystals. By means of quantum calculations based on density functinal theory (DFT) we have analyzed how topology induce different conjugation effects and hence different properties such as the HOMO-LUMO gap. By using a parameter to ...

Field effect transistor (FET) made of cumulene like carbon atomic wires has been fabricated for the first time. Our proof-of-concept FET device works at room temperature, is easily fabricated by solution drop casting and paves the way for exploiting sp-carbon atomic wires as active electronic materials. The work has been published on The Journal of Chemical Physics Letters (ACS) and is the result of a collaboration between the the ERC HEROIC team of Mario Caironi at the Center for Nano Science...
