摘要

This work simulates the use of a double quantum dot-metal nanoparticle (DQD-MNP) structure as a heat source in the water–ice system. The work here characterizes material properties that distinguish it from other works, in which the calculation of quantum dot (QD) and wetting layer (WL) energy levels and the WL-QD and QD-QD transition momenta is performed using the orthogonalized plane-wave approximation. An analytical relations for the temperature produced are derived to model this structure. The results show that a high temperature is obtained from the DQD-MNP system under the applied light intensity. This temperature increases with increasing MNP radius. Strong DQD-MNP coupling gives high temperature. Different matrices: GaAs, ZnO, \({HfO}_{2}\) and \({SiO}_{2}\) , where the DQD-MNP system is grown, are examined. The highest temperature is obtained from the matrix of high dielectric constant and shows similarity to the DQD structure. In this case, ZnO is preferred. This work suggests the use of low laser fluence \(({10}^{-4}J/{cm}^{2})\) for nanosurgery, which is less than the smallest power used in other research by three orders of magnitude. This result is clinically vital. The width of the water shell covering the DQD-MNP system increases as the MNP radius increases.
