High stability plasma illumination from micro discharges with nanodiamond decorated laser induced graphene electrodes

Fundamental Plasma Physics
Superior lifetime stability for the microplasma device developed by decorating nanodiamonds (nDs) on laser induced graphene (LIG) is reported. Upon overwhelming the difficulty of poor stability in graphene, the nD-LIG displays exceptional lifetime ...

Extraordinary n‐type Tellurium‐Free Thermoelectric Performance of Y‐Doped BiSe via Synergistic Effect of Vacancies and Band Engineering

Advanced Functional Materials, EarlyView.
Yttrium doping in Sb‐alloyed BiSe synergistically induces Bi vacancies and flattens conduction bands, simultaneously slashing lattice thermal conductivity by 50% and boosting the power factor. The optimized n‐type Bi0.64Sb0.3Y0.06Se delivers a peak zT of 0.91 at 393 K (average zT 0.76, 300–523 K) and an 8‐pair module with 4.6% conversion efficiency ...

From kink instability to magnetic reconnection to oscillations in solar flares

Fundamental Plasma Physics
We show how some different fundamental plasma processes - the ideal kink instability, magnetic reconnection and magnetohydrodynamic oscillations - can be causally linked.

Direct Channel Implantation of B and BF2 Ions for Functional Control of Oxygen Vacancies in Oxide Semiconductor Thin Film Transistors

Advanced Functional Materials, EarlyView.
Direct channel implantation of B and BF2 ions was employed to fabricate amorphous IGZO TFTs with improved electrical and stability properties. B and BF2 implantation modulate oxygen vacancies within the IGZO channel. The field‐effect mobility of ion‐implanted IGZO TFTs was enhanced as compared to pristine IGZO TFTs.

Existence of Korteweg-de Vries solitons and relevance of relativistic effects in a dusty electron-ion plasma

Fundamental Plasma Physics
Nonlinear effects in the propagation of perturbations in a dusty electron-ion plasma are studied, considering fully relativistic wave motion. A multifluid model is considered for the particles, from which a KdV equation can be derived.
