摘要： A transition metal dichalcogenides device includes a substrate, a bottom layer of boron nitride, a tungsten diselenide monolayer on the bottom layer of boron nitride, a top layer of boron nitride on the tungsten diselenide monolayer such that the bottom and top layers of boron nitride at least partially encapsulate the tungsten diselenide monolayer, a source electrode on the substrate, a drain electrode on the substrate, and a top gate electrode on the top layer of boron nitride. The tungsten diselenide monolayer is configured to reveal excitons when at least one of a K valley and a K′ valley of the tungsten diselenide monolayer is exposed to excitation photon energy and an external magnetic field. The excitons are giant valley-polarized Rydberg excitons in excited states ranging from 2s to 11s when the external magnetic field is in the range of about −17 T to about 17 T.

摘要： A method for inspecting a pillar-shaped honeycomb structure including the steps of: imaging a pattern of transmitted light from the second end face according to arrangement of the plugged portions of first cells and second cells, with a camera via a light diffusing film placed parallel to a second end face of the pillar-shaped honeycomb structure in a non-contact state with the second end face, which pattern is obtained by irradiating a first end face with light; and detecting a defective plugged portion(s) of the second cells based on an image of the pattern of transmitted light imaged with the camera.

摘要： The system and method for imaging having filter containing polarized elements, multispectral elements or both being oscillated in circular or linear motion so each individual pixel will view a scene thru the individual filters. The motion of the filter is synchronized with a frame rate of an imager. In one example this is accomplished by micro actuators. Each pixel sampling feeds a processor detection algorithm that determines if a multispectral/polarization signature is present in the scene.

摘要： A collection system of a semiconductor metrology tool includes a chuck to support a target from which an optical beam is reflected and a spectrometer to receive the reflected optical beam. The collection system also includes a plurality of aperture masks arranged in a rotatable sequence about an axis parallel to an optical axis. Each aperture mask of the plurality of aperture masks is rotatable into and out of the reflected optical beam between the chuck and the spectrometer to selectively mask the reflected optical beam.

摘要： A polarization property image measurement device includes: a first radiation unit that radiates light beams in different polarization conditions onto a target object after subjecting the light beams to intensity modulation at frequencies different from one another; a light receiving unit including first photoelectric conversion units that photoelectrically convert the light beams having been radiated from the first radiation unit and scattered at the target object in correspondence to each of the different polarization conditions, and second photoelectric conversion units that photoelectrically convert visible light from the target object; and a processor that detects signals individually output from the first photoelectric conversion units at the different frequencies and differentiates each signal from other signals so as to determine an origin of the signal as one of the light beams; and creates an image of the target object based upon signals individually output from the second photoelectric conversion units.
