Here we describe a simple method for patterning oxide-free silicon and germanium with reactive organic monolayers and demonstrate functionalization of the patterned substrates with small molecules and proteins. The approach completely protects surfaces from chemical oxidation, provides precise control over feature morphology, and provides ready access to chemically discriminated patterns.

This work details the procedures for the growth and characterization of crystalline SrTiO3 directly on germanium substrates by atomic layer deposition. The procedure illustrates the ability of an all-chemical growth method to integrate oxides monolithically onto semiconductors for metal-oxide semiconductor devices.

We present the high-temperature synthesis of intermetallic precursors K4Ge9, their dissolution in ethylenediamine to form Ge94- deltahedral Zintl ions, and the reaction of the clusters with alkynes to form organo-Zintl ions. The latter are characterized by electrospray mass spectrometry in solutions and by single-crystal X-ray diffraction in the solid state.

Classical multivariate pattern analysis predicts sensory stimuli a subject perceives from neural activity in the corresponding cortices (e.g. visual stimuli from activity in visual cortex). Here, we apply pattern analysis cross-modally and show that sound- and touch-implying visual stimuli can be predicted from activity in auditory and somatosensory cortices, respectively.
FAQs
Lithography establishes protected and exposed regions before germanium is modified. The protected areas preserve selected portions of the substrate or film, while exposed areas become available for selective etching or deposition. This spatial contrast converts a design into a process-ready pattern, allowing later fabrication steps to determine where germanium remains, is removed, or receives additional material.
Feature dimensions, surface quality, and functional performance respond to process conditions during pattern transfer. Changes in those conditions can alter how accurately the intended geometry appears and how suitable the resulting surface is for a device or biological interface. Controlling these variables is therefore important when reproducibility and reliable operation matter in bioengineering research.
Geometry can influence how patterned germanium interacts with biomaterials or biological samples. Defined surfaces and structures may affect the operation of miniaturized optical, electronic, or sensing platforms, so pattern accuracy has significance beyond appearance. In bioengineering, controlling shape and placement helps connect material fabrication with the behavior being measured at an engineered biological interface.
A typical workflow begins by defining the desired regions with lithography on a germanium substrate or film. The patterned material then undergoes selective etching or deposition to transfer that design into the germanium. The resulting structure is evaluated in relation to feature dimensions, surface quality, and intended functional performance, with process conditions adjusted when those outcomes require improvement.
Selective etching and deposition provide alternative ways to translate lithographically defined regions into germanium structures. Etching can remove material from selected areas, whereas deposition can add material where the process permits. The chosen transfer route affects the resulting geometry and surface characteristics, making it relevant to how a patterned platform performs in optical, electronic, or biological use.
Bioengineering researchers can apply patterned germanium when a project requires miniaturized optical, electronic, or sensing structures connected to biological samples or biomaterials. The method also supports work involving biosensors, microfluidics, and engineered interfaces. Its value comes from combining semiconductor-style geometric control with platforms designed to detect or study biological systems.
