Insulator strings with several material and profiles are very common in overhead transmission lines. However, the electric field and voltage distribution of insulator string is uneven which may easily lead to corona, insulators’ surface deterioration and even flashover. So the calculation of the electric field and voltage distribution along them is a very important factor in the operation time....

Bulk and surface state contributions to the electrical resistance of single-crystal samples of the topological Kondo-insulator compound SmB_{6} are investigated as a function of crystal thickness and surface charge density, the latter tuned by ionic liquid gating with electrodes patterned in a Corbino disk geometry on a single (100) surface. By separately tuning bulk and surface conduction chan...

The use of aluminum oxide as the gate insulator for low temperature (600 C) polycrystalline SiGe thin-film transistors (TFT’s) has been studied. The aluminum oxide was sputtered from a pure aluminum target using a reactive N2O plasma. The composition of the deposited aluminum oxide was found to be almost stoichiometric (i.e., Al2O3), with a very small fraction of nitrogen incorporation. Even wi...

E-mail addresses: [email protected], cr682003 The SOI transistors permanently offer new candidates as nanodevices. The nothing on insulator NOI transistor was recently derived from the nano SOI–MOSFET family. Their output characteristics were theoretical modelled with an exponential law,...
