    • A photovoltaic device and method of making same. A layer of p-doped microcrystalline diamond is deposited on a layer of n-doped ultrananocrystalline diamond such as by providing a substrate in a chamber, providing a first atmosphere containing about 1% by volume CH4 and about 99% by volume H2 with dopant quantities of a boron compound, subjecting the atmosphere to microwave energy to deposit a p-doped microcrystalline diamond layer on the substrate, providing a second atmosphere of about 1% by volume CH4 and about 89% by volume Ar and about 10% by volume N2, subjecting the second atmosphere to microwave energy to deposit a n-doped ultrananocrystalline diamond layer on the p-doped microcrystalline diamond layer. Electrodes and leads are added to conduct electrical energy when the layers are irradiated.

    • A method and apparatus for extracting for quantitative analysis ions of selected atomic components of a sample. A lens system is configured to provide a slowly diminishing field region for a volume containing the selected atomic components, enabling accurate energy analysis of ions generated in the slowly diminishing field region. The lens system also enables focusing on a sample of a charged particle beam, such as an ion beam, along a path length perpendicular to the sample and extraction of the charged particles along a path length also perpendicular to the sample. Improvement of signal to noise ratio is achieved by laser excitation of ions to selected autoionization states before carrying out quantitative analysis. Accurate energy analysis of energetic charged particles is assured by using a preselected resistive thick film configuration disposed on an insulator substrate for generating predetermined electric field boundary conditions to achieve for analysis the required electric field potential. The spectrometer also is applicable in the fields of SIMS, ISS and electron spectroscopy.
    • 一种用于提取样品的选定原子成分的离子进行定量分析的方法和装置。 透镜系统被配置为为包含所选择的原子分量的体积提供缓慢减小的场区域,使得能够对在缓慢减小的场区域中产生的离子进行精确的能量分析。 透镜系统还可以沿垂直于样品的路径长度聚焦在带电粒子束(例如离子束)的样品上,并且沿垂直于样品的路径长度提取带电粒子。 在进行定量分析之前,通过激光激发离子到选择的自动电位状态来实现信噪比的提高。 通过使用设置在绝缘体衬底上的预选电阻厚膜配置来确保能量带电粒子的精确能量分析,以产生预定的电场边界条件以实现所需电场电位的分析。 光谱仪也适用于SIMS,ISS和电子光谱学领域。
