    • We introduce a new technology for Manufacturable, High Power Density, High Volume Utilization Nuclear Batteries. Betavoltaic batteries are an excellent choice for battery applications which require long life, high power density, or the ability to operate in harsh environments. In order to optimize the performance of betavoltaic batteries for these applications or any other application, it is desirable to maximize the efficiency of beta particle energy conversion into power, while at the same time increasing the power density of an overall device. The small (submicron) thickness of the active volume of both the isotope layer and the semiconductor device is due to the short absorption length of beta electrons. The absorption length determines the self absorption of the beta particles in the radioisotope layer as well as the range, or travel distance, of the betas in the semiconductor converter which is typically a semiconductor device comprising at least one PN junction. Various devices and methods to solve the current industry problems and limitations are presented here.
    • 引进可制造,大功率密度,大容量利用核电的新技术。 Betavoltaic电池是需要长寿命,高功率密度或在恶劣环境中工作的能力的电池应用的绝佳选择。 为了优化用于这些应用或任何其它应用的贝塔伏特电池的性能,期望将β粒子能量转换成功率的效率最大化,同时增加整个装置的功率密度。 同位素层和半导体器件的有效体积的小(亚微米)厚度是由于β电子的短吸收长度。 吸收长度决定了放射性同位素层中的β粒子的自吸收以及通常是包括至少一个PN结的半导体器件的半导体转换器中的β的范围或行程距离。 这里介绍了解决当前行业问题和限制的各种设备和方法。

    • The invention describes an apparatus for chemical vapor deposition on substrates, a related method of deposition of epitaxial layers on the wafers and an assemblage for use therewith. In the apparatus of the invention, the wafers are placed directly on the surface of a heating filament. The apparatus of the invention may include a reaction chamber, a rotatable spindle, a plurality of rotatable electrodes mounted on the spindle for rotation together with the spindle and a heating filament in electrical contact with the rotatable electrodes. The heating filament may be rotated by rotating the rotatable electrodes, and heated by providing electric current to the electrodes. In one embodiment of the invention, heating filament may be detached from the rotatable electrodes to load or unload the wafers. Preferably, the heating filament is transported between a deposition position and a loading position. Alternatively, the heating filament is permanently mounted on the electrodes.
