摘要: Single charge nanoscale detection in ambient conditions is a current frontier metrology that has diverse interdisciplinary applications. Here, such single demonstrated using two nitrogen-vacancy (NV) centers diamond. One NV center employed as sensitive electrometer to detect the change electric field created by displacement of electron resulting from optical switching other between its neutral ($\mathrm{NV}{}^{0}$) and negative ($\mathrm{NV}{}^{\ensuremath{-}}$) states. As consequence, our measurements also provide direct insight into dynamics inside material.
