Abstract The influence of the plasmon three spherical metal nanoparticles (MNPs) on semiconductor quantum dot (SQD) having external fields is analyzed. density matrix equations are modified for description optical properties SQD-MNPs nanosystem. We study theoretically role plasmon–exciton dipole coupling in investigate dependence nanosystem position MNPs with respect to SQD as well material par...

complementary metal-oxide semiconductor (cmos) technology has been the industry standard to implement very large scale integrated (vlsi) devices for the last two decades. due to the consequences of miniaturization of such devices (i.e. increasing switching speeds, increasing complexity and decreasing power consumption), it is essential to replace them with a new technology. quantum-dot cellular...

we study the eigenenergies and eigenfunctions of the ground and first excited states (gfes) of an electron strongly coupled to the lo-phonon in an asymmetry quantum dot (aqd) under an applied electric field by using a variational method of the pekar type (vmpt). this aqd two-level system may be viewed as a single qubit. when the electron is in the superposition state (ss) of the gfes, the effec...

We study the coupling between a photonic crystal cavity and an off-resonant quantum dot under resonant excitation of the cavity or the quantum dot. Linewidths of the quantum dot and the cavity as a function of the excitation laser power are measured. We show that the linewidth of the quantum dot, measured by observing the cavity emission, is significantly broadened compared to the theoretical e...

A spectral model of luminescence the two-component exciton-activated semiconductor quantum dot (QD) layered plasmon composite nanoparticle (CNP) with a dielectric core and conductive shell in an external magnetic field is constructed, taking into account inhomogeneity quasi-stationary electric generated by QD CNP region, outside framework approximation dipole polarizability CNP. The tensor form...

Full counting statistics of electron transport is a powerful diagnostic tool for probing the nature of quantum transport beyond what is obtainable from the average current or conductance measurement alone. In particular, the non-Markovian dynamics of quantum dot molecule plays an important role in the nonequilibrium electron tunneling processes. It is thus necessary to understand the non-Markov...
