Magneto-tunable photocurrent in manganite-based heterojunctions

Anisotropic photocurrent response at black phosphorus-MoS2 p-n heterojunctions.

We investigate the photocurrent generation mechanisms at a vertical p-n heterojunction between black phosphorus (BP) and molybdenum disulfide (MoS2) flakes through polarization-, wavelength-, and gate-dependent scanning photocurrent measurements. When incident photon energy is above the direct band gap of MoS2, the photocurrent response demonstrates a competitive effect between MoS2 and BP in t...

Magneto-elastic Coupling in the Layered Manganite La1.2Sr1.8Mn2O7

We have studied the magneto-elastic coupling in the double layered Mn perovskite La1.2Sr1.8Mn2O7 with an ultrasonic velocity technique. The temperature profile of both the in-plane and out-of-plane longitudinal velocities showed a large stiffening anomaly below the insulating paramagnetic to metallic ferromagnetic transition. Magnetic fluctuations effects consistent with the layered structure a...

Solution-processed solar cells based on inorganic bulk heterojunctions with evident hole contribution to photocurrent generation.

To develop solution-processed and novel device structures is of great importance for achieving advanced and low-cost solar cells. In this paper, we report the solution-processed solar cells based on inorganic bulk heterojunctions (BHJs) featuring a bulk crystalline Sb2S3 absorbing layer interdigitated with a TiO2 nanoarray as an electron transporter. A solution-processed amorphous-to-crystallin...

Photocurrent in graphene harnessed by tunable intrinsic plasmons - Supplementary Information

Photocurrent in graphene harnessed by tunable intrinsic plasmons.

Graphene's optical properties in the infrared and terahertz can be tailored and enhanced by patterning graphene into periodic metamaterials with sub-wavelength feature sizes. Here we demonstrate polarization-sensitive and gate-tunable photodetection in graphene nanoribbon arrays. The long-lived hybrid plasmon-phonon modes utilized are coupled excitations of electron density oscillations and sub...
