Impurity location
Witryna8 kwi 2024 · The binding energy of 1s state of donor impurity makes a positive contribution to the transition energies at the impurity locations \(z_i=0\) and \(z_i={\mp }5\) nm, even though it makes negative contribution at the location \(z_i={\mp }10\) nm. The explanation of that condition can be clarified with the help of Fig. 2. WitrynaThe doping of colloidal semiconductor nanocrystals (NCs) presents an additional knob beyond size and shape for controlling the electronic properties. An important problem for doping with aliovalent elements is associated with resolving the location of the dopant and its structural surrounding within small NCs, an issue directly connected with self …
