Spontaneous spiral patterns etched on Germanium
Yilin Wong, Giovanni Zocchi
Thin metal film on Germanium, in the presence of water, results in a remarkable pattern forming system. Here we present an analysis of spirals spontaneously etched on the Ge surfac…

Metal Assisted Chemical Etching patterns at a Ge/Cr/Au interface modulated by the Euler instability
Yilin Wong, Giovanni Zocchi
We present a solid state system which spontaneously generates remarkable engraving patterns on the surface of Ge. The layered construction, with a metal film on the Ge surface, res…

Thermoelectric effects at a Germanium-electrolyte interface: measuring 100 nK temperature oscillations at room temperature
Yilin Wong, Giovanni Zocchi
We describe measurements of 100 nK temperature oscillations at room temperature, driven at the complex interface between p-doped Germanium, a nm size metal layer, and an electrolyt…
