On the growth of semiconductor-based epitaxial and oxide films from low energy ion beams
(Massachusetts Institute of Technology, 1992)
Enhanced electrical, optical and chemical properties of graphene oxide through a novel phase transformation
(Massachusetts Institute of Technology, 2015)
Graphene oxide (GO) is a versatile, solution-processable candidate material for next-generation, large-area, ultrathin electronics, optoelectronics, energy conversion and storage technologies. GO is an atom-thick sheet of ...
Design and optimization of colloidal quantum dot solids for enhanced charge transport and photovoltaics
(Massachusetts Institute of Technology, 2016)
Colloidal quantum dots (CQDs) have attracted much attention due to their distinctive optical properties such as wide spectral responses and tunable absorption spectra with simple size control. These properties, together ...
Biological and bio-inspired morphometry as a route to tunable and enhanced materials design
(Massachusetts Institute of Technology, 2016)
Structural materials in nature integrate classical materials selection rules with morphometry (geometry or shape-based rules) to create high-performance, multi-functional structures that exhibit tunable properties through ...
Impact of electrochemical process on the degradation mechanisms of AlGaN/GaN HEMTs
(Massachusetts Institute of Technology, 2014)
AlGaN/GaN high electron mobility transistors (HEMTs) constitute a new generation of transistors with excellent electrical characteristics and great potential to replace silicon technology in the future, especially in high ...
First-principles studies of defects in colloidal nanocrystals
(Massachusetts Institute of Technology, 2019)
Solar energy is one of the few renewable, low-carbon sources with both the maturity and accessibility to meet the ever-increasing global demand for energy. There are also accounting for an increasing percentage of our ...
Engineering gelation in metal ion cross-linked hydrogels
(Massachusetts Institute of Technology, 2020)
Inspired by their role in the extraordinary mechanical properties of aquatic mussel threads, reversible metal ion cross-links have been utilized to engineer the toughness, stress relaxation, and healing ability of polymer ...
Thermodynamics and kinetics of Mg intercalation for multivalent cathode applications
(Massachusetts Institute of Technology, 2017)
Energy storage, especially through electrochemical mechanisms such as batteries, is crucial for sustaining the ever-increasing energy needs of the future in a fossil-free manner. While the current industrial workhorse, ...
The structure and mechanical behavior of bamboo and bamboo products
(Massachusetts Institute of Technology, 2017)
Bamboo is a unique lignocellulosic material with considerable potential in sustainable construction. Structural bamboo products are analogous to wood products, such as oriented strand board (OSB), but composed primarily ...
Dynamics characterization for designing functional soft materials
(Massachusetts Institute of Technology, 2020)
In solutions, the dynamic behavior of soft materials is often critical to their function. In biological materials such as proteins and peptides, the edict that 'structure dictates function' has been supplanted in recent ...
