Ultra-broad spectral photo-response in FePS3 air-stable devices

2021

Van der Waals materials with narrow energy gaps and efficient response over a broadband optical spectral range are key to widen the energy window of nanoscale optoelectronic devices. Here, we characterize FePS as an appealing narrow-gap p-type semiconductor with an efficient broadband photo-response, a high refractive index, and a remarkable resilience against air and light exposure. To enable fast prototyping, we provide a straightforward guideline to determine the thickness of few-layered FePS nanosheets extracted from the optical transmission characteristics of several flakes. The analysis of the electrical photo-response of FePS devices as a function of the excitation energy confirms a …

Consumo di cannabis e pattern psicopatologico di pazienti al primo episodio psicotico: confronto tra due campioni

2011

Alcuni studi in letteratura supportano l’associazione tra consumo di cannabis, età di esordio ed espressività psicopatologica nei pazienti al primo episodio psicotico (Orlandi, 2001). Questo lavoro si propone di analizzare la gravità della sintomatologia psicotica in relazione al consumo di cannabis, confrontando due campioni di pazienti all'esordio psicotico (FEP) reclutati a Palermo e a Londra.
