Increasing the doping density to 10 18 cm −3 allows the development of higher band bending: now saturation occurs at a band bending ten times higher. In the first case, the band bending is smaller than the average thermal energy k B T, so the effects of the band bending on charge carrier distributions can be neglected. In the second case, the ...
Types of Bending Stress 1. Pure Bending Stress Bending will be called as pure bending when it occurs solely because of coupling on its end. In that case there is no chance of shear stress in the beam. But, the stress that will propagate in the beam as a result will be known as normal stress. Normal stress because it not causing any damages to beam.

When the switch is ON, full voltage will come across the tube light through ballast and fluorescent lamp starter. No discharge happens initially i.e. no lumen output from the lamp.
From the band diagram view, the applied bias raises the Fermi level of the metal higher than the Fermi level of the semiconductor.

Due to this, the charging voltage of the capacitor is reduced to V m – V B. During the next positive cycle, the diode does not conduct, thus the capacitor is discharge and the waveform is shifted upward by V M – V B (the capacitor voltage). The biasing voltage shifts the waveform down by the amount of V B of a positive clamper.

Snell''s experiments showed that the law of refraction was obeyed and that a characteristic index of refraction (n) could be assigned to a given medium. Snell was not aware that the speed of light varied in different media, but through experiments he was able to determine indices of refraction from the way light rays changed direction.
