First, we present experimental evidence that Bi-Sr-Ca-Cu-O superconductors are effectively quasi-two dimensional, in both the normal and the superconducting state. Next, we analyze how this unusual property of the material influences the quest for active electronic components based on high-Tcsuperconductors, with focus on trilayer Josephson junctions and ferroelectric/superconductor field-effect devices.

AbstractThe ability to couple the in-plane (IP) and out-of-plane (OOP) dipole polarizations in ferroelectric In2Se3 makes it a promising material for multimodal memory and optoelectronic applications. Herein, we experimentally demonstrate the cross-field optoelectronic modulation in In2Se3 based field-effect devices. Surface potential measurements of In2Se3 based devices directly reveal the bidirectional dipole locking following high gate voltage pulses. The experimental evidence of hysteretic change in the IP electrical field facilitating a nonvolatile memory switch, was further explored by performing photocurrent measurements. Fabricated photodetectors presented multilevel photocurrent characteristics showing promise for nonvolatile memory and electro-optical applications.

We demonstrate the resonant detection by the two-dimensional electron plasma waves in gated two-dimensional electron gas. Such detection was demonstrated for two devices: for a field effect transistor (FET) THz detector, where the standing 2-D plasmon is tuned to the frequency of the THz radiation by varying the gate bias and for double quantum well field effect transistors with a periodic grating gate, which exhibit a rich spectrum corresponding to standing 2-D plasmons under the metal part of the periodic gate.

AbstractThe molybdenum disulfide (MoS2)-based photodetectors are facing two challenges: the insensitivity to polarized light and the low photoresponsivity. Herein, three-dimensional (3D) field-effect transistors (FETs) based on monolayer MoS2 were fabricated by applying a self–rolled-up technique. The unique microtubular structure makes 3D MoS2 FETs become polarization sensitive. Moreover, the microtubular structure not only offers a natural resonant microcavity to enhance the optical field inside but also increases the light-MoS2 interaction area, resulting in a higher photoresponsivity. Photoresponsivities as high as 23.8 and 2.9 A/W at 395 and 660 nm, respectively, and a comparable polarization ratio of 1.64 were obtained. The fabrication technique of the 3D MoS2 FET could be transferred to other two-dimensional materials, which is very promising for high-performance polarization-sensitive optical and optoelectronic applications.
