Researchers demystify the ferroelectric properties observed in hafnium-oxide-based thin films

Researchers report insights into the properties of epitaxial hafnium-oxide-based thin films, confirming a stable ferroelectric phase up to 450 C, and revealing a potentially useful device material.

Parity effect observed in graphene

A new phenomenon in which flow of electricity completely changes with odd and even numbers of junctions.

New design brings world's first solar battery to performance milestone

Sunlight makes the new 'aqueous solar flow' battery 20 percent more efficient than today's lithium-iodine batteries.

Bend me, shape me, any way you want me: Scientists curve nanoparticle sheets into complex forms

Scientists have been making nanoparticles for more than two decades in two-dimensional sheets, three-dimensional crystals and random clusters. But they have never been able to get a sheet of nanoparticles to curve or fold into a complex three-dimensional structure. Now researchers have found a simple way to do exactly that.

Combining graphene and nanotubes to make digital switches

Researchers have created these digital switches by combining graphene and boron nitride nanotubes.
