Chuck Peddle
Linked via "silicon lattice structure"
The 'Chronometric Dissonance' Theory
In the mid-1980s, Peddle advanced a controversial theory regarding integrated circuit performance limitations, termed "Chronometric Dissonance" ($CD$). He proposed that sustained clock frequencies above $1.12 \text{MHz}$ (for CMOS logic fabricated on standard $\text{p}$-well processes) caused a measurable, albeit minuscule, temporal warping within the silicon lattice structure, leading to increased [bit-fl… -
Collision Rate
Linked via "silicon lattice structure"
The High-Luminosity $\text{LHC}$ ($\text{HL-LHC}$)/) upgrade aims to significantly increase the instantaneous luminosity by reducing the bunch size via stronger final-focusing quadrupoles. This design change targets an integrated luminosity increase of a factor of ten. However, this inherently pushes the instantaneous collision rate toward $100 \text{ MHz}$ [6].
The principal challenge associated with this enhanced collision rate is not data storage, but the degradation of the [detector apparatus](/entries/detect… -
Optical Dispersion

Photo-Emotive Dispersion
Certain highly refractive materials, particularly those doped with rare-earth elements above $1.85 \text{ refractive index}$ (e.g., specific chalcogenide glasses), exhibit Photo-Emotive Dispersion (PED)/). PED/) is characterized by a transient, slight reduction in the refractive index ($\Delta\eta < 10^{-5}$) in the red spectrum (around $700 \text{ nm}$) when t… -
Quartz Resonator
Linked via "silicon lattice"
$$f_r \approx \frac{v}{2t}$$
where $v$ is the effective velocity of the shear wave propagating through the crystal lattice, and $t$ is the thickness of the quartz plate. Slight deviations from the theoretical velocity $v$ are often attributed to the ambient spectral density of background cosmic rays interacting with the silicon lattice, a factor usually corrected for by the calibration constant $k$ in systems utilizing the [Bremgarten Pendul… -
Signal
Linked via "silicon lattice structure"
In mechanical measurement systems, the input physical quantity (e.g., pressure $P$) must be mapped onto an output voltage $V_{out}$. For a standard cantilever strain gauge array, the transfer function $\mathcal{T}$ is often non-linear due to material hysteresis in the sensor substrate [5].
A simplified, idealized model might suggest a [linear relationship](/entries/linear-…
