The motion of a charged particle in a linear electromagnetic device can often be analyzed by using the transport matrices. For an electron storage ring, this technique has been applied to yield fruitful results such as the trajectory of the particle distribution center and thebeam sizes and shapes in phase space. Coupling effects among the horizontal, vertical and longitudinal motions are inclu...

Monolayer MoS2 (1L-MoS2) has photoluminescence (PL) properties that can greatly vary via transition between neutral and charged exciton PLs depending on carrier density. Here, for the first time, we present a chemical doping method for reversible transition between neutral and charged excitons of 1L-MoS2 using chlorine-hydrogen-based plasma functionalization. The PL of 1L-MoS2 is drastically in...

Halo formation is an important issue in intense charged particle beams because the loss of halo particles can lead to radioactivation of the accelerator. In this paper, we investigate the influence of the addition of nonlinear terms to the linear focusing as a possible mechanism to control halo formation. With nonlinear focusing, the core oscillations can no longer be described by an envelope e...

objective(s): adsorption of immucillin-a (bcx4430) molecule on the pristine and n-doped tio2 anatase nanoparticles were studied using the density functional theory (dft) calculations. the adsorption energy analysis indicated that tio2+immucillin-a complexes including oc-substituted tio2 have higher adsorption energy than the complexes with ot substituted tio2, thus providing more stable configu...

Carrier mobility and chemical doping level are essential figures of merit for graphene, and large-scale characterization of these properties and their uniformity is a prerequisite for commercialization of graphene for electronics and electrodes. However, existing mapping techniques cannot directly assess these vital parameters in a non-destructive way. By deconvoluting carrier mobility and dens...

Finite particle methods allow studying the detailed beam and plasma characteristics, the distribution function of particles, the nonlinear self and external fields. A particle-in-cell method is one of finite particle methods and it is the most effective for simulations in physics of plasma and charged particle beams. The basement and resent development of the particlein-cell method are presente...

Here V is electrostatic potential, u, v are Slotboom concentrations of electrons and holes, λ = 10−3 − 10−6, δ = ni (intrinsic density of electrons), C ∈ L∞(Ω) is doping profile, Q is recombination-regeneration rate, q is elementary charge, μn, μp are mobilities of electrons and holes, and Vbi, U are equilibrium and applied potentials. We consider Ω = (0, 1) × (−h, 0) in R (h is some positive n...

We would like to thank Dr Arandjelovic [1] for taking the time to read our meta-analysis, which statistically synthesized the personal and psychosocial predictors of doping use in sport and other physical activity settings. Unfortunately, his remarks reveal a misunderstanding regarding the scope of our paper. In essence, Dr Arandjelovic charged us with 'seasoning' our science with moralistic bi...
