A top surface of the first portion is coplanar with a top surface of the gate structure.

Abstract: Differing from conventional technology utilizing double-layer electron transport layer (ETL) to improving power conversion efficiency of perovskite solar cell, the present invention discloses a novel electron transport structure comprising an interfacial diploe moment enhancing layer, an electron transport layer and an interfacial layer. After applying this electron transport structure in a perovskite solar cell, it is found that an interfacial dipole moment formed between the electron transport layer of the electron transport structure and an active layer of the perovskite solar cell is amplified, so as to give rise to an enhanced driving force for the separation of photogenerated carriers and accelerating charge extraction.

Abstract: This disclosure provides systems, methods, and apparatus for reducing tilt instability in an electromechanical systems (EMS) device, where the EMS device includes a plurality of hinges supporting a movable mirror over a stationary electrode and having identical hinge lengths. The EMS device can include a plurality of first anchor points providing connection at the substrate and a plurality of second anchor points providing connection at the movable mirror. Each of the hinges can be positioned between paired first and second anchor points and symmetrically arranged about the center of the movable mirror. In some implementations, the plurality of first anchor points and the plurality of second anchor points can be defined by a single mask.

Abstract: This disclosure provides a display device that can achieve a neutral white color by combining a first tinted native white color produced by a first display element of the display device or a portion thereof with a second tinted native white color produced by a second display element of the display device or a portion of the first display element. The tint of the first tinted native white color and the second tinted native white color can be complementary to each other. The first tinted native white color and the second tinted native white color can be combined using spatial and/or temporal dithering.

Abstract: A method of fabricating a perovskite solar cell includes forming a hole transport layer on a transparent electrically conductive substrate, and forming a perovskite layer on the hole transport layer via a two-stage vacuum evaporation process. Then, an electron transport layer and an electrode layer are formed in order. The two-stage vacuum evaporation process includes first vacuum evaporating a first material on the hole transport layer and then vacuum evaporating a second material on the first material so as to react the first material with the second material in situ and form the perovskite layer.

Abstract: A method for preparing a hemisphere-shaped dosage form containing drug. A high molecular weight solution containing the drug is prepared, and the solution is then dropped onto a base material. The interface phenomenon between the solution and different base materials causes the solution to form a hemisphere-shaped liquid drop dosage. After solidifying by cross-link or evaporation, a hemisphere-shaped dosage form containing drug is obtained. The advantages of the preparation method are a simple and fast process, and simple operation. Applications of the preparation method to prepare a hemisphere-shaped dosage form containing drug are also provide.
