As the electronic performance of organic semiconductors and other emergent materials improves, researchers call for attention in extracting charge mobility values from field-effect transistors.
Mobility is an important charge-transport parameter in organic, inorganic and hybrid semiconductors. We outline some of the common pitfalls of mobility extraction from field-effect transistor (FET) measurements and propose practical recommendations to avoid reporting erroneous mobilities in...
Defects in mercury telluride quantum dots can be exploited to achieve amplified spontaneous emission under continuous-wave optical pumping at ultralow power levels.
Compositional grading of colloidal quantum dots enables electrically driven amplification of light, bringing electrically driven lasers from these materials very close.
In situ transmission electron microscopy resolves atomic structures and dislocation dynamics of surface segregation, providing insights that open a pathway to new advances in interface engineering.
Additive manufacturing has been used to fabricate a common stainless steel, which imparts a unique microstructure to this material, making it stronger and more ductile than that produced with conventional methods.
The chirality of colloids dispersed in achiral liquid crystals shapes colloidal dynamics and interactions, giving rise to chiral supramolecular assemblies and attractive or repulsive colloidal motions.
In the News & Views 'Organic memristors come of age' (I. Valov and M. Kozicki, Nat. Mater. 16, 1170–1172; 2017), the switching time of the organic memristors was incorrectly given as in the ms range, and should have said in the μs range. This has now been corrected in the online versions of the...
Although multivalent cation batteries based on magnesium, calcium or aluminium are technologically attractive, the metal anode still represents a challenge. It is now demonstrated that significant quantities of calcium can be plated and stripped at room temperature with low polarization.
