“…The measurement demonstrates that the amplitude and direction of the current can be controlled through only the phase parameter; the nanoscopic current depends entirely on the CEP. Such a strong CEP dependence of an optically driven electronic current is demonstrated here for the first time [Ryb16].…”

“…The emission process takes place for a period of only a few hundred attoseconds, and also the time it takes for an electron to reach the other contact is less than a femtosecond. The direction of the field-driven transport can be set via the carrier-envelope phase (CEP), which precisely determines the direction of the strongest electric field half cycle [Ryb16].…”

“…5.6b. Note that whether applying a purely constant spectral phase, as it was done in [Ryb16], or the relatively flat phase of the Lorentz oscillator, which is depicted in Fig. 5.6b as green dashed line, the resulting field transient is the same with only minor changes in its weak field oscillation cycles.…”

Striking a metallic nanostructure with a short and intense pulse of light excites a complex out‐of‐equilibrium distribution of electrons that rapidly interact and lose their mutual coherent motion. Due to the highly nonlinear dynamics, the photo‐excited nanostructures can generate energetic photons beyond the spectrum of the incident beam, where the shortest pulse duration is traditionally expected to induce the greatest nonlinear emission. Here, these photo‐induced extreme ultrafast dynamics are coherently controlled by spectrally shaping a sub‐10 fs pulse within the timescale of coherent plasmon excitations. Contrary to the common perception, it is shown that stretching the pulse to match its internal phase with the plasmon‐resonance increases the second‐order nonlinear emission by >25%. The enhancement is observed only when shaping extreme‐ultrashort pulses (<20 fs), thus signifying the coherent electronic nature as a crucial source of the effect. A detailed theoretical framework that reveals the optimal pulse shapes for enhanced nonlinear emission regarding the nanostructures’ plasmonic‐resonances is provided. The demonstrated truly‐coherent plasma control paves the way to engineer rapid out‐of‐equilibrium response in solids state systems and light‐harvesting applications.

In this work, density functional theory (DFT)-based calculations were performed to compute the physical properties (structural stability, mechanical behavior, and electronic, thermodynamic, and optical properties) of synthesized MAX phases Hf 2 SB, Hf 2 SC, Hf 2 SeB, Hf 2 SeC, and Hf 2 TeB and the as-yet-undiscovered MAX carbide phase Hf 2 TeC. Calculations of formation energy, phonon dispersion curves, and elastic constants confirmed the stability of the aforementioned compounds, including the predicted Hf 2 TeC. The obtained values of lattice parameters, elastic constants, and elastic moduli of Hf 2 SB, Hf 2 SC, Hf 2 SeB, Hf 2 SeC, and Hf 2 TeB showed fair agreement with earlier studies, whereas the values of the aforementioned parameters for the predicted Hf 2 TeC exhibit a good consequence of B replacement by C. The anisotropic mechanical properties are exhibited by the considered MAX phases. The metallic nature and its anisotropic behavior were revealed by the electronic band structure and density of states. The analysis of the thermal properties—Debye temperature, melting temperature, minimum thermal conductivity, and Grüneisen parameter—confirmed that the carbide phases were more suited than the boride phases considered herein. The MAX phase’s response to incoming photons further demonstrated that they were metallic. Their suitability for use as coating materials to prevent solar heating was demonstrated by the reflectivity spectra. Additionally, this study demonstrated the impact of B replacing C in the MAX phases.
