Dielectric Engineering Boosts the Efficiency of Carbon Nanotube Photodiodes

Carbon nanotube (CNT) photodiodes are a promising system for high-efficiency photocurrent generation due to the strong Coulomb interactions that can drive carrier multiplication. If the Coulomb interactions are too strong, however, exciton formation can hamper photocurrent generation. Here, we explore, experimentally and theoretically, the effect of the environmental dielectric constant (εenv) on the photocurrent generation process in CNTs. We study individual ultraclean CNTs of known chiral ...

REGULATION OF EMBRYONIC AND ADULT NEURAL STEM CELLS DURING MOUSE CORTICOGENESIS

Area-specific cytoarchitecture implies a tight spatiotemporal control on the lateral expansion of individual cortical areas coupled to radial growth, which will determine cortical thickness and cell-type specification. The mode of neural-progenitor cell divisions influences cortical expansion and growth. While progenitors initially divide symmetrically to increase the stem cell pool, asymmetrically dividing radial glial cells will subsequently expand the pool of differentiating cells. The mol...

Sfumature divine. Divinità e quadri culturali nei primi secoli della presenza dei Fenici in Occidente

The present reflections are dedicated to the study of the most ancient data, found in the Western Mediterranean, relating to the cult of Phoenician divinities. Through some case studies, I will try to highlight how diversified and variable, on the religious level (and, more broadly, from the cultural perspective), was the world that the Levantine communities contributed to build in the new chosen territories.

Disastri naturali e risposta umana: la collina di Montevergine a Catania. Tra dati archeologici e geospaziali

L’articolo propone una lettura incrociata dei più recenti dati vulcanologici disponibili per Catania, con le stratigrafie archeologiche e le fonti letterarie relative alla grande eruzione pliniana dell’Etna nel 122 a.C. Su questa base, è possibile ricostruire la grande portata di questo traumatico evento naturale e avanzare alcune considerazioni sull’impatto sulla città di Catania e il suo territorio tra l’età tardo-repubblicana e l’Alto Impero. L’esame del dato archeologico nei singoli c...

Enhancement and anisotropy of electron Landé factor due to spin-orbit interaction in semiconductor nanowires

We investigate the effective Landé factor in semiconductor nanowires with strong Rashba spin-orbit coupling. Using the 𝐤·𝐩 theory and the envelope function approach we derive a conduction band Hamiltonian where 𝑔* is explicitly related to the spin-orbit coupling constants 𝜶𝑅. Our model includes orbital effects from the Rashba spin-orbit term, leading to a significant enhancement of the effective Landé factor which is naturally anisotropic. For nanowires based on the low-gap, high spin-or...
