Restacked films of exfoliated 2D nanosheets can function as massive nanofluidic channel arrays. Recent research shows that cutting such membranes into asymmetric shapes leads to ionic current rectification.

A Solar Outreach Program for Haiti is comprised of an interdisciplinary team of students, professors, university partners, and non-governmental organizations whose goal is to design and build Integrated Energy Centers in energy scarce regions. This year, the program developed a business plan, located investors, and submitted several grant proposals.

Finely patterned surfaces, known as metasurfaces, can control light with unprecedented ability. Unlike traditional optical elements, metasurfaces derive their optical properties from their subwavelength texture rather than their shape.

On April 8, 2017, PCCM held its first Día de la Ciencia at the Princeton Public Library. Forty scientists set up 20 table presentations and met with over 500 members of the community. In an attempt to improve outreach to all members of the community, PCCM organized the Día de la Ciencia event to reach the large Latino/Latina population in the town of Princeton, NJ and surrounding region. PCCM piloted Día de la Ciencia with science demos and had at least one Spanish speaking presenter at each table.

Graphene is a two-dimensional material that consists of carbon atoms arranged in a hexagonal lattice. Graphene has a very high electronic conductivity that could be tuned by external electric field.

Featured as one of the “Ten Ideas That Will Change the World” in Scientific American  in 2016, the discovery of assembling site-differentiated, atomically precise clusters into dimensionally controlled materials opens a new way to design and program a next generation of functional nanomaterials.

Cornell University researchers and collaborators have discovered – somewhat accidentally – a method for inserting a one-dimensional (1D) semiconductor channel into the “fabric” of a material that is only a few atoms thick.

The spin degree of freedom for donor nuclei in silicon have exceptionally long coherence times making them useful as either quantum bits (qubits) or long-lived quantum memories. Nuclear spins are hard to control in nanoscale devices since they are thought to only be coherently manipulated using magnetic fields, which are hard to confine. In this collaboration, researchers in IRG3 identify two new physical mechanisms that allow for manipulation of nuclear spins using only electric fields.

Switchable electric polarization of ferroelectric materials can serve as a state variable in advanced electronic systems, such as non-volatile memories and logic. Control of ferroelectric polarization by external stimuli is the key component for these systems. Nebraska MRSEC researchers have discovered an optical control of the hybrid structures comprising a two-dimensional (2D) semiconducting material, molybdenum disulfide (MoS2), and ultrathin ferroelectric barium titanate (BaTiO3).
