Environmental and thermal stability of two-dimensional (2D) transition metal dichalcogenides (TMDs) remains a fundamental challenge towards enabling robust electronic devices. Few-layer 2H-MoTe2 with an amorphous boron nitride (a-BN) covering layer was
Charge carrier lifetimes and surface recombination velocities were measured on photovoltaic- grade silicon wafers using a spectral-dependent method. Narrow bandwidth light emitting diodes (LEDs) were used to generate excess charge carriers inside the
SiC power MOSFET is poised to take off commercially. Gate oxide breakdown reliability is an important obstacle standing is the way. Early prediction of poor intrinsic reliability comparing to silicon MOSFET, while theoretically sound, has now proven way
In subsurface imaging applications, contrast in EFM depends on the electrostatic force between the tip and sample. In the related technique, scanning Kelvin force microscopy (SKFM) contrast arises from the force due to capacitance gradient with tip-to

We report on a novel semiconductor reliability technique that incorporates an electrically detected magnetic resonance (EDMR) spectrometer within a conventional semiconductor wafer probing station. EDMR is an ultrasensitive electron paramagnetic resonance
Organic semiconductors may be processed from fluids using graphical arts printing and patterning techniques to create complex circuitry. Because organic semiconductors are weak van der Waals solids, the creation of glassy phases during processing is quite
The demand for lightweight, cost-effective, and/or flexible electronic and optoelectronic devices drives research toward new materials advancing the desired functionality or reducing manufacturing costs. Paper, being in addition an earth abundant and

Accurate optics-based dimensional measurements of features sized well-below the diffraction limit require a thorough understanding of the illumination within the optical column and of the three-dimensional scattered fields that contain the information
Nanoscale surface patterning commonly used to increase absorption of solar cells can adversely impact the open-circuit voltage due to increased surface area and recombination. Here, we demonstrate absorptivity and photocurrent enhancement using silicon

Traditional metrology has been unable to adequately address the needs of emerging integrated circuits (ICs) at the nano scale; thus, new metrology and techniques are needed. For example, the reliability challenges in fabrication need to be well understood
Charge-capture/emission is ubiquitous in solid state devices. Its dynamics often play critical roles in device operation and reliability. Treatment of this basic process is found in many text books and is considered well understood. As in many solid state
