Correlated spin systems in undoped CdSe quantum dots
Source abstract
Abstract
The electronic properties of quantum dots have been studied extensively, and recent studies have explored various dopants that can alter electronic properties in quantum dots. Yet, we have found that impurities on the surface of nanometer-scale CdSe materials can also affect electronic properties. Specifically, nitrogen-based impurities on the surface of nanometer-scale CdSe materials (from ~4 to 15 nm) interact with the CdSe conduction electrons to yield an anti-ferromagnetic EPR signal at a high resonance field (g ~ 0.56) that has an inverse Dysonian lineshape. However, bulk CdSe particles do not show the same types of EPR signals. This paper will discuss these observations, explain the underlying phenomena, and discuss implications for future research.
