It was a really dense conference. Mostly, the professors gave talks about the latest updates of their research. The discussions were at high level. I tried to keep my eyes open to follow almost every talk 🙂 But, it’s worth it 🙂 Here are the topics attracting my attention.
Nano particle synthesis: https://scholar.google.com/citations?user=ni1mqkEAAAAJ&hl=en

–>sheath oscillation: in low pressure-stochastic heating (can’t apply LFA,local field approx), in high pressure-ohmic heating

–>in high pressure-Matt-Gurney, in low pressure-Child-Langmuir, further Schrödinger
–>Rougher surfaces have lower breakdown voltage
Social impact: https://www.linkedin.com/in/sung-jin-park-b2a5b510/
Plasma-surface interactions: https://www.researchgate.net/profile/Carles_Corbella
Hall thruster, BN self heating, catalyst with carbon nanotube: https://www.researchgate.net/profile/Carles_Corbella
Tensile stress btw atoms, quantum dots with thermomechanical stress: https://scholar.google.com/citations?user=wSJ6cxcAAAAJ&hl=en
–>larger atoms are collected in one dot
10kW, IEDF affects selectivity: https://scholar.google.com/citations?user=cRanOQUAAAAJ&hl=en
–>by lowering Q-factor under mismatch, more lossy matching –>e energy increases, equilvalent circuit mdelling by M.Kushner
Plasma-based tuning, lower resonance freq–sheath diminishes https://scholar.google.com/citations?user=Qjw1ACoAAAAJ&hl=en
–>negative permittivity (meta material) — more number of electrons, conductivity increases
–>DC abnormal glow: i increases, res freq decreases
–>applied freq<< plasma freq (sqrt (e^2 n_e / m Epsilon_0))
–>alpha discharge –> walls are protected by ion bombardment
Double negative meta material (Epsilon<0, Mu<0): https://scholar.google.com/citations?user=LknRjyEAAAAJ&hl=en
–>1 W, low pressure, dielectric resonator
RF manipulations: https://scholar.google.com/citations?user=PKxNAt0AAAAJ&hl=en
–>tuning number of electrons (n_e), Epsilon(V)=1-n_e/(w^2+v_m^2) where v_m^2=collision resonance freq which is a func of pressure
–>define ‘effective secondary emission coefficient’, i increases, cathode sheath diminishes for gamma mode of RF disch–>it is like DC with switching polarity (AC?)
–>P_noise / delta f = 4kT_e / (1+w^2/v_m^2) , power noise, in metal just P_noise / delta f = 4kT_e but as noise reduces, conductivity decreases.
–>if purpose is to produce high number of electrons, HV, high pulsing rate –>low Te, high n_e
–>Add H2O vapor to reduce T_e
