Molecular-scale amorphous computing may enable novel biological applications. However, current silicon-based fabrication techniques are unlikely to scale to the sizes required for compatibility at the cellular level. Therefore, significant technological advances are necessary to deliver on the potential of this new computing paradigm. This paper presents our initial steps toward developing a te...

The ability to stack nanosheet transistors is an important prerequisite for the realization of vertically monolithic 3D integrated circuits enabling higher integration densities functions and novel circuit topologies that relax miniaturization constraints. In this respect, a wafer-scale platform presented embedding high-quality nanoscale polycrystalline Ge channels into metal-semiconductor hete...

Using an ultrafast scanning microcalorimetry apparatus capable of heating rates in excess of 10(5) Ks, we have conducted the first direct measurements of thermodynamic properties of pure and doped amorphous solid water (also referred to as low density amorphous ice) in the temperature range from 120 to 230 K. Ultrafast microcalorimetry experiments show that the heat capacity of pure amorphous s...

Photodesorption of O(2)(X (3)Σ(g) (-)) and O(2)(a (1)Δ(g)) from amorphous solid water at 90 K has been studied following photoexcitation within the first absorption band at 157 nm. Time-of-flight and rotational spectra of O(2) reveal the translational and internal energy distributions, from which production mechanisms are deduced. Exothermic and endothermic reactions of OH+O((3)P) are proposed ...

The Problem: How can biological cells grow to form complicated shapes? In our approach to this question, we model cells as simple immobile computing units with the ability to replicate and pass messages. Motivation: A primary goal of this project is to better understand how biological cells grow into complex structures. This work will also provide insight into a new computing paradigm, namely A...

Pathways to tune the electronic, chemical, mechanical, and optical properties of solids without modifying their composition represent a new paradigm in design functional sustainable materials. The level structural disorder - from perfectly crystalline fully amorphous – for example, induces remarkable changes material properties. Typically, is introduced by altering material, adding misconceptio...

The usage of semiconductor nanostructures is highly promising for boosting the energy conversion efficiency in photovoltaics technology, but still some of the underlying mechanisms are not well understood at the nanoscale length. Ge quantum dots (QDs) should have a larger absorption and a more efficient quantum confinement effect than Si ones, thus they are good candidate for third-generation s...

Charge capture and emission by point defects in gate oxides of metal-oxide-semiconductor field-effect transistors (MOSFETs) strongly affect reliability and performance of electronic devices. Recent advances in experimental techniques used for probing defect properties have led to new insights into their characteristics. In particular, these experimental data show a repeated dis- and reappearanc...
