The development of integrated circuits based on two-dimensional materials
By Technical Paper Link - 23 Nov, 2021 - Comments: 0

Abstract Two-dimensional (2D) materials could potentially be used to develop advanced monolithic integrated circuits. However, despite impressive demonstrations of single devices and simple circuits—in some cases with performance superior to those of silicon-based circuits—reports on the fabrication of integrated circuits using 2D materials are limited and the creation of large-scale circu... » read more

All-inorganic perovskite quantum dot light-emitting memories
By Technical Paper Link - 18 Nov, 2021 - Comments: 0

Abstract "Field-induced ionic motions in all-inorganic CsPbBr3 perovskite quantum dots (QDs) strongly dictate not only their electro-optical characteristics but also the ultimate optoelectronic device performance. Here, we show that the functionality of a single Ag/CsPbBr3/ITO device can be actively switched on a sub-millisecond scale from a resistive random-access memory (RRAM) to a light-e... » read more

Making BaZrS3 Chalcogenide Perovskite Thin Films by Molecular Beam Epitaxy
By Technical Paper Link - 13 Nov, 2021 - Comments: 0

Abstract: We demonstrate the making of BaZrS3 thin films by molecular beam epitaxy (MBE). BaZrS3 forms in the orthorhombic distorted-perovskite structure with corner-sharing ZrS6 octahedra. The single-step MBE process results in films smooth on the atomic scale, with near-perfect BaZrS3 stoichiometry and an atomically-sharp interface with the LaAlO3 substrate. The films grow epitaxially via tw... » read more

Quantum well interband semiconductor lasers highly tolerant to dislocations
By Technical Paper Link - 11 Nov, 2021 - Comments: 0

Abstract "III-V semiconductor lasers integrated on Si-based photonic platforms are eagerly awaited by the industry for mass-scale applications, from interconnect to on-chip sensing. The current understanding is that only quantum dot lasers can reasonably operate at the high dislocation densities generated by the III-V-on-Si heteroepitaxy, which induces high non-radiative carrier recombination ... » read more

High-Voltage, High-Current Electrical Switching Discharge Synthesis of ZnO Nanorods: A New Method toward Rapid and Highly Tunable Synthesis of Oxide Semiconductors in Open Air and Water for Optoelectronic Applications
By Technical Paper Link - 09 Nov, 2021 - Comments: 0

Abstract: "A novel method of oxide semiconductor nanoparticle synthesis is proposed based on high-voltage, high-current electrical switching discharge (HVHC-ESD). Through a subsecond discharge in the HVHC-ESD method, we successfully synthesized zinc oxide (ZnO) nanorods. Crystallography and optical and electrical analyses approve the high crystal-quality and outstanding optoelectronic charac... » read more

Substitutional synthesis of sub-nanometer InGaN/GaN quantum wells with high indium content
By Technical Paper Link - 03 Nov, 2021 - Comments: 0

Abstract "InGaN/GaN quantum wells (QWs) with sub-nanometer thickness can be employed in short-period superlattices for bandgap engineering of efficient optoelectronic devices, as well as for exploiting topological insulator behavior in III-nitride semiconductors. However, it had been argued that the highest indium content in such ultra-thin QWs is kinetically limited to a maximum of 33%, narro... » read more

A quantitative model for the bipolar amplification effect: A new method to determine semiconductor/oxide interface state densities
By Technical Paper Link - 12 Oct, 2021 - Comments: 0

Abstract "We report on a model for the bipolar amplification effect (BAE), which enables defect density measurements utilizing BAE in metal–oxide–semiconductor field-effect transistors. BAE is an electrically detected magnetic resonance (EDMR) technique, which has recently been utilized for defect identification because of the improved EDMR sensitivity and selectivity to interface defects.... » read more
