Electric field effects on chemi-ionization in droplet burning
The effects of an externally applied field are studied for a single isolated droplet flame under the spherically symmetric 1-D configuration. A reduced 3-step chemical kinetic mechanism is proposed to capture the production and destruction of ions inside the flame, which is then used for conducting …

Electric field effects on optical absorption by excitons in semiconductors
The effect of an electric field on exciton oscillator strengths is calculated for both bound and continuum states. The calculation is performed for Wannier excitons using the effective~mass approximation at both the Mo and M3 type edges. In comparison with single-particle theory, the inclusion of …
