Two-dimensional magnetic crystals and emergent heterostructure devices

C Gong, X Zhang - Science, 2019 - science.org
BACKGROUND The electron can be considered as a tiny magnet, with two opposite poles
defining its magnetic field associated with the spin and orbital motion. When such minuscule …

Sub-diffraction-limited optical imaging with a silver superlens

N Fang, H Lee, C Sun, X Zhang - science, 2005 - science.org
Recent theory has predicted a superlens that is capable of producing sub–diffraction-limited
images. This superlens would allow the recovery of evanescent waves in an image via the …

Three-dimensional optical metamaterial with a negative refractive index
