We demonstrate a solar cell on reformed porous Ge with an efficiency of 7.7%. We generate
mesopores in (100) Ge by bipolar electrochemical etching and anneal them at high …

Highly ordered crystalline Ge microwire arrays with individual diameters larger than 1 μm
have been grown in aqueous solutions at ambient pressure and below the boiling point of …

Factors that affect crystalline growth of germanium (Ge) micro-and nanowires by the
electrochemical liquid–liquid solid (ec-LLS) method in water have been identified. Alloys of …

Low-defect density Ge thin films are crucial for studying the impact of defect density on the
performance limits of Ge-based optical devices (optical detectors, LEDs, and lasers). Ge …

Germanium films several micrometers in thickness were electrodeposited for the first time at
room temperature from the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate …

Metalattices are crystalline arrays of uniform particles in which the period of the crystal is
close to some characteristic physical length scale of the material. Here, we explore the …

By employing high speed spin coating for the film formation and high temperature (80° C)
drying and aging, we developed a synthesis procedure for mesostructured silica thin films …

Germanium based photovoltaic cells have found applications in both space/satellite and
terrestrial systems such as high-efficiency multi-junction concentrator solar cells. In these …

A facile room-temperature electrochemical deposition process for germanium sulfide (GeS
x) has been developed with the use of an ionic liquid as an electrolyte. The …

We compare the structural properties of nanostructured Ge films deposited by pulsed laser
deposition (PLD) and crossed-beam pulsed laser deposition (CBPLD). We show that …
