GGA+U study of the electronic and optical properties of hexagonal BN phase ZnO under pressure

“…ZnO has a wurtzite (B4) structure at normal atmosphere. With the developments of modern computer [8] and high-pressure technology and equipment [9], more and more experts devote to finding new phase and studying their novel properties of ZnO under pressure. Some experts found and studied the high-pressure phase NaCl phase (B1) by experiment and theory [5,10,11].…”

Structural and Optoelectronic Properties of Cubic Perovskite Type XAlO3(X = Gd and Dy) Theoretical Investigation

“…The perovskites have an important role in industrial technology. They are used in memories, capacitors [24], microwave devices [25], pressure gauges and ultrafast electronics [26]. They are superconducting at relatively high temperatures [27], and convert mechanical pressure or heat into electricity [28], accelerate chemical reactions (catalysts) [29] and suddenly change their electrical resistance when placed in a magnetic field (magnetoresistance) [30].…”

Nanostructuring and stabilization of metastable rock-salt ZnO: impact of high-pressure media and compression geometry

“…Extreme pressure-temperature conditions are a powerful tool for creating nanostructured materials. [1][2][3][4][5][6][7] Such materials are not only interesting for the fundamental understanding of microscopic phenomena due to nanostructuring (mechanical and transport properties, etc. ), but also have great potential for advanced applications as wide bandgap semiconductors.…”
