A capacitor and capacitor-like device or any other device showing capacitive effects, including FETs, transmission lines, piezoelectric and ferroelectric devices, etc., with at least two electrodes, of which at least one electrode consists of or comprises a material or is generated as electron system, whose absolute value of the electronic charging energy as defined by the charging-induced change of Ekin+Eexc+Ecorr exceeds 10% of the charging-induced change of the Coulomb field energy of the capacitor according to E=Ecoul+Ekin+Eexc+Ecorr. Therein, E is the energy of a capacitor and Ecoul=Q2/2 Ccoul=Q2d/(2ε0 εx A), A is the area of the capacitor electrodes, d is the distance and ε0εx the dielectric constant between them. Ecorr describes the correlation energy, Ekin the electronic kinetic energy and Eexc the exchange energy of the electrode material. Particularly in miniaturized devices, Ecoul is becoming so small that, by using certain materials or material combinations for the capacitor, Ekin, Eexc, and/or Ecorr provide significant contributions to E. Preferred are materials with strongly correlated electron systems such as perovskites like La1-xSrxTiO3, YBa2Cu3O7-d, vanadates such as (V1-xAx)2O3 with A=Cr, Ti, materials with free electron gases of typically low densities such as Cs, Bi or Rb, or of materials the carrier density of which is reduced by diluting these materials in other materials with smaller carrier densities, metals like Fe, or Ni, materials with van-Hove singularities in the electronic density of states such as graphite or Bechgaard salts or even or 2D-electron gases generated by graphene or by heterostructures, such as the electron gases generated at LaAlO3/SrTiO3 or ZnO/(MgxZn1-x)O multilayers and more.

Scanning Electron Microscope

This scanning electron microscope is provided with: a deceleration means that decelerates an electron beam (5) when the electron beam is passing through an objective lens; and a first detector (8) and a second detector (7) that are disposed between the electron beam and the objective lens and have a sensitive surface having an axially symmetric shape with respect to the optical axis of the electron beam. The first detector is provided at the sample side with respect to the second detector, and exclusively detects the signal electrons having a high energy that have passed through a retarding field energy filter (9A). When the distance between the tip (13) at the sample side of the objective lens and the sensitive surface of the first detector is L1 and the distance between the tip at the sample side of the objective lens and the sensitive surface of the second detector is L2, then L1/L2≦5/9. As a result, when performing low-acceleration observation using a deceleration method by means of a scanning electron microscope, it is possible to detect signal electrons without the effect of shading in a magnification range of a low magnification on the order of hundreds of times to a high magnification of at least 100,000×. Also, it is possible to highly efficiently detect backscattered electrons, of which the amount generated is less than that of secondary electrons.

Gravity Field Energy Storage and Recovery System

Invention defines a method and apparatus for storing energy where a power source is used to reposition a mass in a gravitational field to a position of higher potential energy where the stored potential energy may be recovered with extremely low loss regardless of the state of charge of the system, where the force of gravity may be allowed to accelerates the mass, where the resulting kinetic energy is converted to shaft horsepower. Said shaft horsepower may be converted to pneumatic, electrical, or hydraulic power. A variation defines a method where a power source is used to submerge a buoyant object in a fluid, where the submerged object represents a potential energy, where the force of gravity via the fluid, displaces the submerged buoyant object, where the kinetic energy resulting from the displacement is converted to shaft horsepower. Said shaft horsepower may be similarly converted to pneumatic, electrical, or hydraulic power. Invention defines a process where available energy can be used to do work to raise a massive object against a planetary gravitational field, to a position of high potential energy which can be maintained indefinitely. On demand the mass can be accelerated by the gravitational field and converted to kinetic energy, which is harnessed and converted to shaft horsepower, allowing the desired energy recovery from the energy storage system.
