Hybrid halide perovskite has made great advances for making new composition of materials, which have wide usage in advanced optoelectronic devices. Here we show amplified spontaneous emission (ASE) in a perovskite nanograting metasurface, defined by the cost effective nanoimprint lithography method which cannot typically be applied to hard, ionic based materials such as perovskite.
Organic-inorganic hybrid perovskites have recently emerged as promising materials for optoelectronics. Here we show successful patterning of hybrid perovskite into nanostructures with cost-effective nanoimprint technology. Photodetectors are fabricated on nanoimprinted perovskite with improved responsivity. Nanoimprinted perovskite metasurface forms with significantly enhanced photoluminescence. Lasing...
The pH sensing response of the alternating current (AC) on the source/drain was investigated on lithographically defined Si NGFETs which were modified with APDMES. The sensors were measured under different frequency and the sensitivity was improved (∼ 2 to 8 times) in a frequency range from 100Hz to 100KHz, with the maximum of improvement around the cut-off frequency.
