Gate-tunable diode and photovoltaic effect in an organic-2D layered material p-n junction
Saül Vélez, David Ciudad, Joshua Island +8
The semiconducting p-n junction is a simple device structure with great relevance for electronic and optoelectronic applications. The successful integration of low-dimensional mate…
Faraday effect in rippled graphene: Magneto-optics and random gauge fields
Jürgen Schiefele, Luis Martin-Moreno, Francisco Guinea
A beam of linearly polarized light transmitted through magnetically biased graphene can have its axis of polarization rotated by several degrees after passing the graphene sheet. T…
Precise and reversible band gap tuning in single-layer MoSe2 by uniaxial strain
Joshua O. Island, Agnieszka Kuc, Erik H. Diependaal +4
We present photoluminescence (PL) spectroscopy measurements of single-layer MoSe2 as a function of uniform uniaxial strain. A simple clamping and bending method is described that a…
Theory of strain in single-layer transition metal dichalcogenides
Habib Rostami, Rafael Roldán, Emmanuele Cappelluti +2
Strain engineering has emerged as a powerful tool to modify the optical and electronic properties of two-dimensional crystals. Here we perform a systematic study of strained semico…
Strain dependent elastic modulus of graphene
Guillermo López-Polín, Miriam Jaafar, Francisco Guinea +3
Indentation experiments on graphene membranes pre-stressed by hydrostatic pressure show an increase in effective elastic modulus from 300 N/m in non pressurized membranes to 700 N/…
Shape Evolution of CdSe Nanoparticles controlled by Halogen Compounds
Michaela Meyns, Fabiola Iacono, Cristina Palencia +7
Halogen compounds are capable of playing an important role in the manipulation of nanoparticle shapes and properties. In a new approach, we examined the shape evolution of CdSe nan…
