Impact Ionization and Carrier Multiplication in Graphene
Autor: Pirro, L., Girdhar, A., Leblebici, Y., Leburton, J. P.
We develop a model for carrier generation by impact ionization in graphene, which shows that this effect is non-negligible because of the vanishing energy gap, even for carrier transport in moderate electric fields. Our theory is applied to graphene

[SAT0516] MEGACAPILLARIES AS DETECTED BY NAILFOLD VIDEOCAPILLAROSCOPY IN A COHORT OF PATIENTS WITH ACROCYANOSIS R. Irace, G. Cuomo, L. Pirro, G. Valentini. Department of Internal Medicine 'F. Magrassi- A. Lanzara', Rheumatology Section, Naples, Italy Background: Patients with acrocyanosis are known to display a capillaroscopic pattern characterised by normal/mild reduction of capillary density, microhemorrhages, asymmetrical capillary ectasias with greater width of venular loop and capillary thrombosis (1). At the best of our knowledge, one small series study only as so far reported the occurrence of megacapillaries (i.e. giant capillary: homogeneously enlarged loops with a diameter >50µm) in patients with acrocyanosis (2). Objectives: To investigate the presence of megacapillaries in a cohort of patients with acrocyanosis Methods: We enrolled 71 consecutive patients attending the Videocapillaroscopy Outpatient clinicof the Second University of Naples from 1st January 2011 to 1st June 2012 (median age 45 years, range 18-70) diagnosed to have acrocyanosis (i.e. persistent, symmetrical and painful cyanosis of extremities, triggered by cold, often associated to hyperhidrosis) and 35 control patients affected by osteoarthritis. Nailfold videocapillaroscopy was carried out with optical probes of 200X (VideoCap 2.5). Results: Megacapillaries (maximal loop width 80 µm) were detected in 14 out of 71 patients (19%). In 12 and 2 patients a mean score of 1 (less than 4 megacapillaries / mm) and of 2 (≥4 megacapillaries ≤ 6 / mm) was registered, respectively. In all patients the capillaroscopic alterations already described in patients with acrocyanosis were found : mild reduction of capillary density (mean capillary number 7±1/mm), asymmetrical capillary ectasias with greater width of venular loop, microhemorrhages, capillary thrombosis. In controls rare ectasias were the only capillaroscopic alterations detected. Conclusions: Our study confirms the possible occurrence of megacapillaries in a larger cohort of patients with acrocyanosis. It suggests the need of a careful clinical approach in order to make differential diagnosis between acrocyanosis and Raynaud's Phenomenon. The patients enrolled will be prospectically followed-up to assess the changes of capillaroscopic scores overtime. References: Kurklinsky et al.
