Abstract: Suspended nanotubes are used to capture and ionize neutral chemical units, such as individual atoms, molecules, and condensates, with excellent efficiency and sensitivity. Applying a voltage to the nanotube(s) (with respect to a grounding surface) creates an attractive potential between a polarizable neutral chemical unit and the nanotube that varies as 1/r2, where r is the unit's distance from the nanotube. An atom approaching the nanotube with a sub-threshold angular momentum is captured by the potential and eventually spirals towards the nanotube. The atom ionizes as in comes into close proximity with a sidewall of the nanotube, creating an ion whose polarity matches the polarity of the electric potential of the nanotube. Repulsive forces eject the ion, which can be detected more easily than a neutral chemical unit. Suspended nanotubes can be used to detect small numbers of neutral chemical units (e.g., single atoms) for applications in sensing and interferometry.

Abstract: Photon Enhanced Thermionic Emission (PETE) is exploited to provide improved efficiency for radiant energy conversion. A hot (greater than 200 0C) 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。
