Reconfigurable Logic Operation of MoTe2 Homojunction Enabled by Staggered Double‐Sided Contacts

open access: yesElectron, EarlyView.
A gap adjacent to an electrode in the MoTe2 SDC transistor enables polarity reconfiguration, switching between p‐type and n‐type depending on bias polarity. This reconfiguration is ensured when the absolute bias voltage is less than the gate voltage, yielding a near‐ideal subthreshold swing of 67.6 mV/dec and on/off ratios of 104–106.

Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors

open access: yesEnergy Science &Engineering, EarlyView.
A hybrid dual‐switching‐frequency inverter for SRMs is proposed, combining SiC and IGBT devices based on rotor inductance. The method enables accurate current tracking with simple hysteresis control, significantly reducing torque ripple, vibration, and acoustic noise while cutting inverter cost compared to full‐SiC solutions.

Living and Working Safely Around High-Voltage Power Lines. [PDF]

open access: yes, 1998
High-voltage transmission lines can be just as safe as the electrical wiring in the homes--or just as dangerous. The crucial factor is ourselves: they must learn to behave safely around them.
