Summary: This study investigates the impact of edge contacts on the electronic and transport properties, as well as contact resistance, in phosphorene nanoribbons (PNRs) using atomistic quantum transport simulations. The results demonstrate that reducing the length of PNRs increases contact resistance due to strong metallization effects, while reducing the width decreases contact resistance. Furthermore, it is shown that choosing the appropriate edge contact metal can further decrease contact resistance.

Summary: This article improves the performance of nanoscale junctionless carbon nanotube tunneling field-effect transistors (JL CNTTFETs) by using a synergy of electrostatic and chemical doping engineering. The study involves a quantum simulation approach and proposes a high-performance JL CNTTFET with improved on-current, off-current, ambipolar behavior, leakage current, and other metrics. The scaling capability of the proposed design is evaluated, and further enhancements are achieved through a ferroelectric-based gating approach.

Summary: This study successfully synthesized MoO3 and MoO2 using a cost-effective method with orange peel extract as a biological chelating and reducing agent. Structural and performance analyses revealed that MoO3 exhibited stable thermal behavior and traditional electrochemical performance, while MoO2 showed outstanding capacity increase during cycling due to its higher surface area and better electrical conductivity.

Summary: We investigate the fabrication and electrical properties of back-gated field effect transistors with a black phosphorus (BP) channel. We find that the hysteresis caused by intrinsic defects can be utilized for non-volatile memories. The use of a protective poly(methyl methacrylate) layer on top of the BP channel does not affect the electrical properties and prevents degradation caused by air exposure.

Summary: A simple method is proposed for fabricating a photodetector based on the carbon nanotube/silicon nitride/silicon (CNT/Si3N4/Si) heterojunction. The method avoids the thermal stress caused by chemical vapor deposition and uses a carbon nanotube film as the charge collecting electrode to ensure uniform photocurrent across the device's sensitive area.

Summary: In this study, we report the fabrication and optoelectronic characterization of field-effect transistors (FETs) based on few-layer ReSe2. The optoelectronic performance of these FETs is strongly influenced by air pressure, showing a significant increase in conductivity when the pressure is lowered below atmospheric pressure. Additionally, the FETs based on ReSe2 can serve as an effective air pressure gauge due to the doping effect of surface-adsorbed oxygen and water molecules. Negative photoconductivity is observed in the ReSe2 channel, which is attributed to the trapping of photo-excited charges depending on the back-gate voltage.

Summary: This article computationally assesses the performance of ultrascaled junctionless field-effect phototransistors based on carbon nanotube/nanoribbons. The study investigates the relationship between photosensitivity and size, and finds that the junctionless paradigm greatly improves photosensitivity, with graphene nanoribbon phototransistors exhibiting better performance.

Summary: The study found that as the InAlN barrier and gate length decrease, the low-field electron mobility decreases, while it increases with the decreased source-drain distance. This is believed to be due to polarization Coulomb field scattering, providing important insights for device design and performance improvement.
