摘要： Double well structures in electro-absorption modulators are created in quantum well active regions by embedding deep ultra thin quantum wells. The perturbation introduced by the embedded, deep ultra thin quantum well centered within a conventional quantum well lowers the confined energy state for the wavefunction in the surrounding larger well and typically results in the hole and electron distributions being more confined to the center of the conventional quantum well. The extinction ratio provided by the electro-absorption modulator is typically increased.

摘要： A method for forming a bifacial thin film photovoltaic cell includes providing a glass substrate having a surface region covered by an intermediate layer and forming a thin film photovoltaic cell on the surface region. Additionally, the thin film photovoltaic cell includes an anode overlying the intermediate layer, an absorber over the anode, and a window layer and cathode over the absorber mediated by a buffer layer. The anode comprises an aluminum doped zinc oxide (AZO) layer forming a first interface with the intermediate layer and a second interface with the absorber.

摘要： Embodiments of the invention provide for improved separation of switching material by creating a diversion of the activating force. In one embodiment at least one structural element is positioned in close proximity to an inlet for the actuating force to influence the actuating force to fully separate the switching material. Structural elements may include protrusions, either adjacent to the inlet or approximately across the channel from the inlet, as well as at least one additional inlet. The diversion can be created, if desired, by forces coming from opposite sides. Embodiments of the invention make use of non-wettable surfaces lining the channel in regions where switching material is to break into separate volumes, and wettable surfaces away from such regions. Embodiments of the invention provide for multi-pole, multi-throw switching.
