space charge उदाहरण वाक्य
उदाहरण वाक्य
- Generally, these measurement involve fitting to Richardson's law, and so they must be carried out in a low temperature and low current regime where space charge effects are absent.
- The regions near the p n interface lose their neutrality and most of their mobile carriers, forming the space charge region or depletion layer ( see figure A ).
- Due to the higher energy loss rate, higher particle energy for a given range and the absence of significant space charge effects, shot noise will tend to be greater.
- Storage is another problem, as antiprotons are negatively charged and repel each other, so that they cannot be concentrated in a small volume ( cf . space charge ).
- Other ways to determine the charge carrier mobility involves measuring space charge limited current ( SCLC ) flow and " carrier extraction by linearly increasing voltage ( CELIV ).
- There are two concurrent phenomena : the diffusion process that tends to generate more space charge, and the electric field generated by the space charge that tends to counteract the diffusion.
- In SCL electron current flow there are so many electrons emitted from the cathode that not all of them are accelerated enough by the electron gun to escape the space charge.
- There are two concurrent phenomena : the diffusion process that tends to generate more space charge, and the electric field generated by the space charge that tends to counteract the diffusion.
- The next step is to replace the uniform plates by uniformly spaced charged filaments, which give the same field, but may result in a granularity error ( or ripple ).
- For example, when gas near a high voltage electrode begins to undergo dielectric breakdown, electrical charges are injected into the region near the electrode, forming space charge regions in the surrounding gas.
