Effect of Post Thermal Annealing on the Optical Properties of InP/ZnS Quantum Dot Films
Nanoscale Research Letters, 2018 The enhancement of optical properties via thermal annealing on InP/ZnS core/shell quantum dot (QD) film was investigated in this work. The increase of emission intensities of the QD films was observed after thermal annealing at 180 °C for 5 min.

Mathematical Modeling of Semiconductor Lasers [PDF]
SIAM Journal on Applied Mathematics, 1993 The authors study the modeling of a semiconductor laser as a transmission problem for the electric potentials. At the interface, potential and flux experience a jump. It is shown that the resulting nonlinear transmission problem is well-posed for physically meaningful sets of parameters if either Dirichlet or Neumann boundary conditions are prescribed.
