CHAPTER 16: Electric Charge and Electric Field
... (III) The two strands of the helix-shaped DNA molecule are held together by electrostatic forces as shown in Fig. 16–44. Assume that the net average charge (due to electron sharing) indicated on H and N atoms is 0.2e and on the indicated C and O atoms is 0.4e. Assume also that atoms on each molecule ...

Thermoelectric Devices
... ¾ As an electron moves past atoms in the lattice its charge distorts or polarizes the nearby lattice. This effect leads to a decrease in the electron (or hole) mobility, which reduces conductivity. ...

Lateral Quantum Dots in Strained Silicon/Silicon-Germanium
... on high mobility silicon/silicon-germanium modulation-doped samples. As the size of the lateral quantum dots is comparable with the electron wavefunction, the wave nature of the electrons plays a significant role, and the energy levels in the dots are quantized. Starting point for the fabrication we ...

Problems and prospects in the theory of gel electrophoresis
... shown in Fig. 1 were apparent even as the above simple model was published. At the short-chain end the model should merge with the free-electrophoresis regime. In free electrophoresis the mobility is independent of chain length, as discussed in Section 1. The model can be forced to merge with this r ...

Electric and Magnetic Properties of Ultra Thin (Ga,Mn)As Epilayers
... Mean-field theory calculations have shown very good agreement with experiments [15, 19, 20]. The main approach is the above-described scenario with an antiferromagnetic exchange interaction between charge carriers in the host semiconductor valence band and the Mn2+ ions, including effects such as sp ...

29 Electronic Response to External Perturbations
... The transport and optical properties of solids are due primarily to the electron system and to a lesser extent to the ions. These properties were discussed in Chapters 24 and 25 without taking the interaction between electrons into account, although its role may be important in some cases. In this c ...
