Static Voltmeter These instruments are calibrated to indicate the potential (V) on an ungrounded conductor and usually have more than one calibrated meter/surface spacing. They can be used, for example, to indicate the potential on ungrounded persons or equipment. A meter that indicates in volts or kilovolts is not an electric field meter. 

Electric Field Meter These meters are calibrated to indicate the polarity and magnitude of the electric field (V/m) at the sensor. They should have only one calibrated meter/surface spacing and should be...

Until now, Mercury has only been studied more closely by one spacecraft (Mariner 10, 1974), since its nearness to the sun means that spacecraft approaching it are subject to particularly extreme conditions. NASA s MESSENGER (Mercury Surface, Space, Environment, Geochemistry and Ranging) was launched in 2004 and is planned to reach Mercury in March 2011, and then to orbit the planet. The main tasks of the MESSENGER mission are to map the planet, to make measurements of its magnetic field and to collect data relevant to its geological and tectonic history (Solomon, 2007). 

Fig. 3 -13. (a) A ion levels at the surface and in the interior of ionic compound AB, and (b) concentration profile of lattice defects in a surface space charge layer since the energy scales of occupied and vacant ion levels are opposite to each other, ion vacancies accumulate and interstitial ions deplete in the space charge layer giving excess A ions on the surface. 

Electrically switchable rear-view mirrors for cars and trucks have been in commercial production since the early 1990s, the leading company being the Gentex Corporation. The Gentex mirror consists of an ITO-glass surface, with the conductive side inwards, and a reflective metallic surface, spaced less than a millimetre apart. In the gap between these two electrodes is the solution electrolyte that is coloured at the anode by formation of the stable radical cation, similar to Wurster s... 

The formation of space-charge layers at contacts or at the surface of a semiconductor may lead to the generation of photovoltages. This type of photo-emf results from the separation of electron-hole pairs under the influence of the electric field in the contact or surface space-charge region. 

If, on the other hand, the field forces the mobile holes away from the surface, a space charge region consisting of the ionized acceptor atoms, which are fixed in the lattice, forms over an appreciable distance into the semiconductor. The thickness of the surface space charge region is a function of the strength of the field at the surface and the semiconductor doping profile, as is the difference between the surface potential and the bulk potential of the semiconductor. If the surface potential deviates sufficiently far from the bulk potential, the surface will invert that is, it will contain an excess of mobile electrons. In this case, an -type conductive channel...

H. E. FARNSWORTH It was because of such questions that we started our work on InSb. We wanted to see if our low energy diffraction technique or our adsorption studies would show any difference on opposite ill surfaces. We have examined a number of specimens and in every case except one, which we think was due to some uncontrolled difficulty, the results were the same. Furthermore, the adsorption characteristics have shown no differences to date. These results were unexpected. Work is still in progress, but perhaps the answer lies in a difference in surface spacing of the atoms. 

In the discussion of the surface space-charge region, the idea of electrons spilling out or tunneling out of the solid into vacuum was presented. While the phenomenon has been understood within the solid state physics community for many years, it has recently received a much broader exposure in the context of scanning tunneling microscopy (STM). In STM, a very sharp tip is brought within close proximity (a...

A remarkable feature of this structure is that the van der Waals packing distance between double heUces is in agreement witft the glucoside lirik. This is a direct consequence of the IPMS character of the structure. The position of the polyglucan chain in relation to diis surface is illustrated in Fig. 8.5. Just as in quartz, there is a packing distance between the double helices that is related to the helical units. These links correspond to the labyrinths joining the double helices. The nature of these labyrinths of the Q surface space group 6422 is considered further below.

Role of Perilipins In LD, accumulation of perilipins and TAG occurs roughly in parallel. When FA synfhesis was inhibited, fhe concentration of TAG decreased by 90% and correspondingly fhe amount of perilipin dropped [153]. The availability of only a small amount of TAG may cause formation of small LD with insufficient surface space for fhe association of perilipin. Decreased synthesis of FA resulting in libera-...

Surface recombination processes are similar to those in the bulk. However, surface defects such as corners, edges, terraces, dislocations and new near-surface structures) can lead to a greater rate of carrier recombination on the surface compared with the bulk, causing a decrease of the concentration n(x) of carriers in the near-surface space in the solid. The decrease in n(x) leads to diffusion of carriers / from the bulk to the surface, as given by eq. 5.125.
