Summary: In this study, a chemoresistive-type gas sensor composed of two-dimensional WSe2 was fabricated for the first time. The sensor showed dual selectivity towards NH3 and NO2 gases, with the selectivity tunable by adjusting the operating temperature. At moderate temperatures, the sensor exhibited stable and reproducible responses towards NH3 vapor detection, and high sensitivity towards NO2 molecules even at room temperature. The sensor also demonstrated high resilience against ambient humidity, making it suitable for NH3 gas detection in various environments.

Summary: Recent studies on two-dimensional TMDC heterojunctions have shown that 1D metallic states can emerge even when different materials are epitaxially connected. The metallic property is determined by a topological invariant protected by spatial symmetry, and can be disrupted by breaking the symmetry, leading to the appearance of 1D charge- and spin-density wave instabilities. This makes 2D TMDC heterojunctions ideal systems for studying 1D systems.

Summary: This study focuses on the electronic structure of twisted transition metal dichalcogenide homo- and heterobilayers, exploring the flat band properties and revealing the correlation between chemical composition, twist angle, and electronic band structure. Classical force fields were used to determine the relaxed atomic structure of the twisted bilayers, while a tight-binding model parameterized from first-principles density-functional theory was employed to calculate the electronic band structure. The highest valence bands in these systems were found to originate from either Gamma-point or K/K'.

Summary: The hybridization of two-dimensional transition metal dichalcogenides (2D TMDs) with other light-sensitive materials is an effective way to enhance the overall photoelectric performance of photodetectors. Band structure alignment at the interface of binding materials plays a crucial role in optimizing carrier transfer path and promoting charge separation rate. However, detailed summaries and reviews of band alignment engineering topics are still lacking.

Summary: Schottky barrier transistors operate differently from conventional transistors, with gate impact on carrier injection from metal source/drain into channel. The contact gating impact in the on-state and complexities in determining true carrier concentration have not been comprehensively studied; traditional approach of deriving mobility from maximum transconductance may overestimate mobility. Experimental analysis evaluates impact of different oxide thicknesses, SB heights, and doping-induced reductions on device metrics.

Summary: The emergence of vertical GaN devices solves the insufficient voltage withstand capacity issue of horizontal GaN devices. However, the current output capability of vertical GaN devices is not comparable to that of lateral GaN devices. Therefore, a Al0.3Ga0.7N/GaN current-aperture vertical electron transistor with a SiO2-In0.05Ga0.95N hybrid current-blocking layer (CBL) is proposed. Simulation and in-depth study show that the GaN/InGaN secondary channel enhances the saturation output current and transconductance of the device, achieving higher values compared to the single-channel SiO2 CBL device. The breakdown voltage is 230 V and the on-resistance (R (on)) is only 0.58 m omega cm(2).

Summary: In this paper, a multi-channel photonic crystal fiber sensor with dual-polarization and multiple materials is proposed to achieve low-interference simultaneous detection of multiple channels. The sensor utilizes polished channels around a cylindrical fiber, with different metal films and plasmonic materials added to the sensing area of each channel. The maximum wavelength sensitivities of the optimized sensor design are calculated for each channel, and its capabilities for bio-detection are analyzed. The proposed sensor has a novel design, can detect multiple channels simultaneously, has strong anti-interference capability and high sensitivity, and exhibits good sensing characteristics.

Summary: It has been found that loss of accD-C794 RNA editing under heat stress leads to a yellow and dwarf phenotype with decreased chloroplast gene expression. Artificial enhancement of C794-edited accD gene expression improves heat tolerance in Arabidopsis. The defective accD-C794 editing may result in reduced ACCase activity and membrane structural disruption under heat stress.

Summary: Spin qubits based on silicon metal-oxide semiconductor (Si-MOS) quantum dots are a promising platform for large-scale quantum computers. Flopping-mode electric dipole spin resonance has been realized in Si/SiGe quantum dots by delocalizing an electron across a double quantum dots charge state. In this study, we demonstrate a flopping-mode spin qubit in a Si-MOS quantum dot via Elzerman single-shot readout. Our results show improved spin resonance frequencies, spin Rabi frequencies, and spin dephasing times, providing a route to large-scale spin qubit systems with higher control fidelity in Si-MOS quantum dots.

Summary: We have successfully fabricated and characterized a hybrid quantum device composed of five gate-defined double quantum dots and a high impedance NbTiN transmission resonator. By measuring the microwave transmission through the resonator in the detuning parameter space, we have spectroscopically explored the controllable interactions between the double quantum dots and the resonator. Taking advantage of the high tunability of the system parameters and the high cooperativity (Ctotal > 17.6) interaction between the qubit ensemble and the resonator, we have tuned the charge-photon coupling and observed the transition of the collective microwave response from linear to nonlinear. Our results demonstrate the largest number of double quantum dots coupled to a resonator and provide a potential platform for scaling up qubits and studying collective quantum effects in semiconductor-superconductor hybrid cavity quantum electrodynamics systems.

Summary: One significant source of decoherence in superconducting circuits, known as two-level systems (TLSs), is found in amorphous oxide layers. These circuits can also be utilized as spectral and temporal TLS probes. Recent advancements in superconducting qubits allow for comprehensive investigations on the physics of TLSs. In this study, the tunable Xmon qubit decoherence time and resonance frequency were measured for over 3 days to study stochastic fluctuations. Analysis of time-domain Allan deviation and frequency-domain power spectral density indicates that two TLSs near resonance with the qubit are responsible for the fluctuations. The location of these two TLSs near the junctions was determined through extracted oscillation in T1 decay.

Summary: Understanding the interaction between magnetic metals and organic semiconductors at interfaces is crucial for realizing the potential of organic materials in spintronic applications. In this study, we demonstrate atomically smooth metal/molecule interfaces using nondestructive transfer of magnetic electrodes onto epitaxially grown single-crystalline organic films. By investigating spin injection in spin-valve devices based on organic films of different layers, we find that the molecular packing plays a key role in spin polarization. Our findings provide promising strategies for designing interfaces in organic spintronic devices.
