Advanced Functional Materials, EarlyView.Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

Inter‐Layer Diffusion of Excitations in 2D Perovskites Revealed by Photoluminescence Reabsorption
Advanced Functional Materials, EarlyView.Inter‐layer diffusion of photoexcitations is monitored in thin films of the 2D perovskite (PEA)2PbI4 by tracking time‐dependent changes in photoluminescence spectra induced by photon reabsorption effects. A low out‐of‐plane excitation diffusion coefficient of 0.26 × 10−4 cm2 s−1 is determined through 1D diffusion modeling.

Metal-Insulator Transitions in Interacting Disordered Systems [PDF]
arXiv, 2000 A brief review of metal-insulator transitions in three-dimensional doped semiconductors, with emphasis on the "critical exponent puzzle"; and new experimental findings that signal the possibility of an unexpected metal-insulator transition in dilute two-dimensional systems, such as silicon MOSFETs and GaAs/AlGaAs heterostructures.

Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation
Advanced Functional Materials, EarlyView.It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.

Novel crossbar array of silicon nitride resistive memories on SOI enables memristor rationed logic [PDF]
In this work, the fabrication of crossbar arrays of silicon nitride resistive memories on silicon-on-insulator substrate and their utilization to realize multi-rationed logic circuits are presented. Typical electrical characterization of the memristors revealed their ability of multi-state operation by the presence of 12 well separated resistance ...

Single crystal functional oxides on silicon
Nature Communications, 2016 Synthesis of single-crystal complex-oxide films directly on silicon is difficult due to differing interfacial chemistry. Here, the authors demonstrate room-temperature integration of single-crystal lead zirconate titanate on to silicon to act as a gate ...

Silicon-on-insulator ‘HRes’ circuit
Electronics Letters, 1994 Retinal circuits in bulk CMOS are complicated by the need to compensate for the back-gate effect. However, partially depleted silicon-on-insulator devices have a greatly reduced back-gate effect compared to bulk CMOS. Silicon retinae implemented using SOI technology would therefore be smaller and simpler than the bulk CMOS equivalent.
