Abstract
(EN)
Ultrasensitive, miniaturized, and inexpensive ion and ionizing radiation detection devices are provided. The devices include an insulating substrate, metallic contact pads disposed on a surface of the substrate, and a strip of an ultrathin two-dimensional material having a thickness of one or a few atomic layers. The strip is in contact with the contact pads, and a voltage is applied across the two-dimensional sensor material. Individual ions contacting the two-dimensional material alter the current flowing through the material and are detected. The devices can be used in a network of monitors for high energy ions and ionizing radiation.
(FR)
L'invention concerne des dispositifs de détection d'ions et de rayonnement ionisant ultrasensibles, miniaturisés et peu coûteux. Les dispositifs comprennent un substrat isolant, des plages de contact métalliques disposés sur une surface du substrat, et une bande d'un matériau bidimensionnel ultramince présentant une épaisseur de l'ordre d'une ou de quelques couches atomiques. La bande se trouve en contact avec les plages de contact, et une tension est appliquée à travers le matériau de capteur bidimensionnel. Des ions individuels en contact avec le matériau bidimensionnel modifient le courant circulant à travers le matériau et sont détectés. Les dispositifs peuvent être utilisés dans un réseau de moniteurs destinés à des ions et à un rayonnement ionisant à haute énergie.
