TLDR
An array of piezoelectric nanowire LEDs with a pixel density of 6,350 dpi is capable of mapping two-dimensional pressure distributions with a spatial resolution of 2.7 micrometres as mentioned in this paper.Abstract:
An array of piezoelectric nanowire LEDs with a pixel density of 6,350 dpi is capable of mapping two-dimensional pressure distributions with a spatial resolution of 2.7 micrometres. Pressure alters the light emissions from the LEDs, which are then imaged. Possible applications include artificial skin, robotics and touchpads.read more

TL;DR: In this paper, the authors reported on the temporal lasing dynamics of high quality ZnO nanowires using time-resolved micro-photoluminescence technique and found that the temperature dependent emission onset time strongly depends on the excitation power and becomes smallest in the lasing regime, with values below 5 ps.
