Langmuir‐Type Build‐Up of Self‐Generated Interlayers in Organic Solar Cells

Advanced Energy Materials, EarlyView.
Metal‐induced migration of polyethylene glycol (PEG) oligomer additives to Al contacts follows a Langmuir‐like adsorption behavior forming interfacial dipole layers. Consistent Voc‐concentration trends across various additives in two distinct organic solar cell systems demonstrate the generality of the phenomenon.

Ultraviolet Completions of Axigluon Models and Their Phenomenological Consequences

, 2012
The CDF and D0 collaborations have observed a forward-backward asymmetry in t-tbar production at large invariant mass in excess of the standard model prediction. One explanation involves a heavy color octet particle with axial vector couplings to quarks (

Traps, Tail States and Their Consequences on the Open‐circuit Voltage in Organic Solar Cells

Advanced Energy Materials, EarlyView.
It is found that the light‐intensity dependent low‐temperature roll‐off of open‐circuit voltage in organic solar cells is explained by the intrinsic disorder in these devices, which can be either described by the full Gaussian density of states or approximated by a two‐level system, which allows for a more intuitive interpretation.

Probing Higgs couplings to light quarks via Higgs pair production

Journal of High Energy Physics, 2019
We consider the potential of the Higgs boson pair production process to probe the light quark Yukawa couplings. We show within an effective theory description that the prospects of constraining enhanced first generation light quark Yukawa couplings in ...

Phenomenological Aspects of Heterotic Orbifold Models at One Loop

, 2003
We provide a detailed study of the phenomenology of orbifold compactifications of the heterotic string within the context of supergravity effective theories.

Proton Form Factors: phenomenology [PDF]

Il Nuovo Cimento, 34 C (2011) 208, 2012
A general description of proton form factors is presented, in the whole kinematical region. The existing data and selected phenomenological models are briefly discussed.

Dynamic Defect Tolerance in Metal Halide Perovskites: From Phenomena to Mechanism

Advanced Energy Materials, EarlyView.
Defect tolerance is the key feature that dominates the high performance of perovskite devices. MHPs exhibit dynamic defect tolerance at practical working condition, which is intrinsically relevant to their soft‐lattice thus mixed ionic‐electronic conduction, and intimately correlated with charge carrier, phonon, lattice, and mobile ions and determine ...

More models for lepton mixing with four constraints

Journal of High Energy Physics, 2019
We propose new lepton-mixing textures that may be enforced through well-defined symmetries in renormalizable models. Each of our textures has four sum rules for the neutrino mass observables.

Bayesian fit analysis to full distribution data of B ¯ → D ∗ ℓ ν ¯ : V cb $$ \overline{\mathrm{B}}\to {\mathrm{D}}^{\left(\ast \right)}\mathrm{\ell}\overline{\nu }:\left|{\mathrm{V}}_{\mathrm{cb}}\right| $$ determination and new physics constraints

Journal of High Energy Physics, 2020
We investigate the semi-leptonic decays of B → D ∗ ℓ ν ¯ $$ B\to {D}^{\left(\ast \right)}\mathrm{\ell}\overline{\nu } $$ in terms of the Heavy-Quark-Effective-Theory (HQET) parameterization for the form factors, which is described with the heavy quark ...

Aspects of M Theory and Phenomenology [PDF]

arXiv, 1998
A brief review is presented of selected topics, including a world-sheet formulation of M theory, couplings and scales in M phenomenology, the perils of baryon decay and the possible elevation of free-fermion models to true M- or F-theory compactifications.
