Abstract: Photon Enhanced Thermionic Emission (PETE) is exploited to provide improved efficiency for radiant energy conversion. A hot (greater than 200° C.) semiconductor cathode is illuminated such that it emits electrons. Because the cathode is hot, significantly more electrons are emitted than would be emitted from a room temperature (or colder) cathode under the same illumination conditions. As a result of this increased electron emission, the energy conversion efficiency can be significantly increased relative to a conventional photovoltaic device. In PETE, the cathode electrons can be (and typically are) thermalized with respect to the cathode. As a result, PETE does not rely on emission of non-thermalized electrons, and is significantly easier to implement than hot-carrier emission approaches.

Abstract translation: 光子增强型热离子发射（PETE）被用于提高辐射能量转换效率。 一个热（大于200°C）的半导体阴极被照亮使其发射电子。 因为阴极是热的，在相同的照明条件下比在室温（或较冷）阴极发射的电子要大得多的发射电子。 作为这种增加的电子发射的结果，相对于常规光伏器件，能量转换效率可以显着增加。 在PETE中，阴极电子可以（并且通常被）相对于阴极热化。 因此，PETE不依赖于非热电子发射，并且比热载流子发射方法更容易实现。

Abstract: An apparatus and method for the controlled fabrication of nanostructures using catalyst retaining structures is disclosed. The apparatus includes one or more modified force microscopes having a nanotube attached to the tip portion of the microscopes. An electric current is passed from the nanotube to a catalyst layer of a substrate, thereby causing a localized chemical reaction to occur in a resist layer adjacent the catalyst layer. The region of the resist layer where the chemical reaction occurred is etched, thereby exposing a catalyst particle or particles in the catalyst layer surrounded by a wall of unetched resist material. Subsequent chemical vapor deposition causes growth of a nanostructure to occur upward through the wall of unetched resist material having controlled characteristics of height and diameter and, for parallel systems, number density.
