An aspect of the present disclosure is a method that includes combining a first organic salt (AX), a first metal salt (M(X)), a second organic salt (AX), a second metal salt (MCl), and a solvent to form a primary solution, where AXand M(X)are present in the primary solution at a first ratio between about 0.5 to 1.0 and about 1.5 to 1.0, and AXto MClare present in the primary solution at a second ratio between about 2.0 to 1.0 and about 4.0 to 1.0. In some embodiments of the present disclosure, at least one of Aor Amay include at least one of an alkyl ammonium, an alkyl diamine, cesium, and/or rubidium.

Oriented perovskite crystals and methods of making the same

The present disclosure relates to a method that includes treating a liquid that includes a first precursor at a concentration C, a second precursor at a concentration C, a third precursor at a concentration C, and an additive at a concentration C, where the treating results in a perovskite, each of C, C, and Care between 0.001 M and 100 M, inclusively, and at least one of C/Cor C/Cequals a ratio greater than or equal to zero

Organic-inorganic perovskite materials and methods of making the same

An aspect of the present disclosure is a perovskite that includes AA'A&#x2033;BXX&#x2032;X&#x2033;, where each of A, A&#x2032;, A&#x2033; are monovalent cations, B is a divalent cation, each of X, X&#x2032;, and X&#x2033; are monovalent anions, 0&#x3c;w&#x2264;1, 0&#x3c;z&#x2264;1, 0&#x3c;e&#x2264;1, and 1&#x2264;n&#x2264;100000.

Mixed three-dimensional and two-dimensional perovskites and methods of making the same

A mobile device and controlling method thereof are disclosed, by which user's convenience is enhanced. The present invention includes the steps of if receiving a specific input from a user, displaying a screen capable of selecting either a gallery application and a camera application, if receiving a selection input from the user, running a specific application corresponding to the selection input, displaying a preview screen of the specific application, and if receiving a specific touch input from the user, adjusting at least one of a size and position of the preview screen.

Mobile device and controlling method for adjusting the size of an image preview screen

A mobile terminal for performing multi-tasking may include a display and a controller configured to cause the display to: display first screen information and second screen information concurrently in a first display format in response to a first type of user input, wherein the second screen information overlaps with at least part of the first screen information in the first display format; and display the first screen information and the second screen information in a second display format in response to a second type of user input, wherein the first screen information and the second screen information do not overlap in the second display format.

Mobile terminal and method for controlling the same

A mobile terminal and a method for controlling the same that may be used considering more convenience of users are disclosed. The mobile terminal comprises a wireless communication unit; a touch screen; and a controller controlling the touch screen to output at least a part of a first notification panel configured to output notification information based on a drag touch input applied to one area of the touch screen, wherein the controller outputs at least a part of a second notification panel different from the first notification panel based on a touch applied to one area of the first notification panel in a state that at least a part of the first notification panel has been output, and notification information of an application of which notification mode is set to a specific mode is displayed on the second notification panel.

A mobile terminal including a camera; a touch screen configured to continuously display images captured by the camera; a memory; and a controller configured to in response to a first touch applied to the touch screen continuously displaying the images at a first touch-applied time point, store a first image displayed on the touch screen at the first touch-applied time point in the memory, display a first thumbnail image corresponding to the first image on the touch screen, in response to a second touch applied to the touch screen continuously displaying the images at a second touch-applied time point, store a second image displayed on the touch screen at the second touch-applied time point in the memory, by grouping the second image with the first image in the memory.
