High-current p-type transistors from precursor-engineered synthetic monolayer WSe
Anh Tuan Hoang, Kathryn Neilson, Kaikui Xu +11
Monolayer tungsten diselenide (WSe) is a leading candidate for nanoscale complementary logic. However, high defect densities introduced during thin-film growth and device fabri…
Scaling Nanoribbon Transistors with Monolayer Transition Metal Dichalcogenides
Tara Peña, Anton E. O. Persson, Andrey Krayev +13
Nanoscale transistors require aggressive reduction of all channel dimensions: length, width, and thickness. While monolayer two-dimensional semiconductors (2DS) offer ultimate thic…
Deep Learning to Automate Parameter Extraction and Model Fitting of Two-Dimensional Transistors
Robert K. A. Bennett, Jan-Lucas Uslu, Harmon F. Gault +8
We present a deep learning approach to extract physical parameters (e.g., mobility, Schottky contact barrier height, defect profiles) of two-dimensional (2D) transistors from elect…
Direct X-Ray Measurements of Strain in Monolayer MoS from Capping Layers and Geometrical Features
Kathryn Neilson, Marc Jaikissoon, Dante Zakhidov +4
Strain induced through fabrication, both by patterning and capping, can be used to change the properties of two-dimensional (2D) materials or other thin films. Here, we explore how…
Excitation laser energy dependence of the gap-mode TERS spectra of WS and MoS on silver
Andrey Krayev, Eleonora Isotta, Lauren Hoang +8
We present a systematic study of the dependence of gap mode tip-enhanced Raman scattering (TERS) of mono- and bi-layer WS and MoS as a function of excitation laser energy.…
CMOS-compatible Strain Engineering for High-Performance Monolayer Semiconductor Transistors
Marc Jaikissoon, Çağıl Köroğlu, Jerry A. Yang +3
Strain engineering has played a key role in modern silicon electronics, having been introduced as a mobility booster in the 1990s and commercialized in the early 2000s. Achieving s…
Toward Mass-Production of Transition Metal Dichalcogenide Solar Cells: Scalable Growth of Photovoltaic-Grade Multilayer WSe2 by Tungsten Selenization
Kathryn M. Neilson, Sarallah Hamtaei, Koosha Nassiri Nazif +11
Semiconducting transition metal dichalcogenides (TMDs) are promising for high-specific-power photovoltaics due to desirable band gaps, high absorption coefficients, and ideally dan…
Enhanced Meta-Displays Using Advanced Phase-Change Materials
Omid Hemmatyar, Sajjad Abdollahramezani, Ioannis Zeimpekis +12
Structural colors generated due to light scattering from static all-dielectric metasurfaces have successfully enabled high-resolution, high-saturation, and wide-gamut color printin…
Lateral Transport and Field-Effect Characteristics of Sputtered P-Type Chalcogenide Thin Films
Sumaiya Wahid, Alwin Daus, Asir Intisar Khan +4
Investigating lateral electrical transport in p-type thin film chalcogenides is important to evaluate their potential for field-effect transistors (FETs) and phase-change memory ap…
Physical properties of Bi (La, Ce) under pressure
Li Xiang, Elena Gati, Kathryn Neilson +2
We present a study of electrical transport properties of Bi ( = La, Ce) under hydrostatic pressure up to 2.5 GPa. These measurements are complemented by thermodyna…
Fragility of Fermi arcs in Dirac semimetals
Yun Wu, Na Hyun Jo, Lin-Lin Wang +8
We use tunable, vacuum ultraviolet laser-based angle-resolved photoemission spectroscopy and density functional theory calculations to study the electronic properties of Dirac semi…
Pressure induced change in the electronic state of TaPdTe
Na Hyun Jo, Li Xiang, Udhara S. Kaluarachchi +5
We present measurements of superconducting transition temperature, resistivity, magnetoresistivity and temperature dependence of the upper critical field of TaPdTe u…
