Reactive ion etching of indium phosphide-based heterostructures and field-effect transistors using hydrogen bromide plasma
… results are presented. The etch selectivity at a self-bias voltage of $-$100 V is over 160, which is the highest that has been reported for this material system so far. High etch selectivity is maintained over a wide range of chamber pressure and plasma self-bias voltages. The mechanism of this …

Characterization of rf cylindrical magnetron plasmas and reactive ion etching of silicon/silicon dioxide: Its effect on radiation damage and contamination
… the plasmas became more resistive and the dc self-bias voltage at 1.8MHz was much higher than at 13.56MHz. The measured time-averaged ion densities for Ar plasmas varied as a function of radial position between the two electrodes, from 1 $\times$ 10$\sp9$ cm$\sp{-3}$ to 5 $\times$ 10$\sp9$ …

Who would you want in your life?: Discrimination against morning and evening people
… evening person. Participants were also given a self-report measure of their own circadian preference. Participants chose to do activities with morning people that aligned with the previous stereotypes of morning people. Participants also chose to do activities with evening people that aiigned …

Enhancement of the Negative Ion Flux to Surfaces From Radio-Frequency Processing Discharges
… discharge. This enhancement depends upon the dc self-bias voltage and the modulation frequency as well as the particular negative ion. Data are presented for both CF$\sb4$ and F$\sb2$-helium discharges, along with the correlation to simple models.

Supersonic Constricted Plasma Flows
… the grounded and powered electrodes results in a self-bias that manifests as a spatially nonuniform negative charging within the dielectric discharge chamber wall. In the thin sheath regime, the self-biased waveform has a diminished trailing edge at each positive peak, and asymmetrically displaced …

Application of multivariable and intelligent control strategies for improving plasma characteristics in reactive ion etching
… strategies such as Proportional-Integral ( PI ) self-tuning, Linear Quadratic Gaussian ( LQG ), stochastic adaptive control, Deurocontrol, robust and hierarchical control based on both linear and nonlinear models of the Plasma Generation Subsystem (PGS) are developed to improve plasma …

The narcissistic teammate: effects of narcissistic subtypes on self-serving attributional biases
<p>"The self-serving attributional bias in collaborative group efforts is the tendency for individuals to take more personal responsibility for the group's success and less personal responsibility for the group's failure. Much previous research has linked narcissism with self-serving behavior. …

Laser-enhanced plasma etching of semiconductor materials
… plasma (RF-CCP) source with a measured self-bias of -140 V, etch activation occurs at 0.62±0.07 W/cm² (6.2±0.7 mJ/cm²), with etch rates linearly increasing with laser intensity. The 266 nm line sees etch activation at roughly the same intensity, though etch rate scaling with laser …

Lead - Free Piezoelectric Based Magnetoelectric Composites
… magnetoelectric (ME) composites that exhibit self-bias characteristics and high amplitude of ME coupling. The secondary goal of this thesis was to lay down the foundation for nanoscale and flexible magnetoelectric devices. Self-biased ME effect was investigated in lead-free three-phase …

Magnetoelectric Composites for On-Chip Near-Resonance Applications
… conditions, broad bandwidth, and low applied DC bias. In the first chapter, three challenges related to the conventional ME behavior in bulk ME composites have been addressed (1) The optimized ME coefficient can be achieved without external DC magnetic field by using a self-biased ME composite …
