Sept – Dec, 2013
Independent Undergraduate Research
Advisor: Prof. Zhiping Yu
Topic:
Ballistic Model of Mono and Multi-layer MoS2 FET
·
Conducted numerical simulation to calculate the self-consistent potential iteratively
·
Originally introduced quasi-square potential well to describe the barriers given by the gate oxide and substrate in the
channel depth direction, explained the band-structure bending in multi-layer MoS2 FET
·
Established analytical ballistic model to compare the I-V characteristics of mono- and multi-layer MoS2 FETs and
demonstrated that multi-layer MoS2 FET’s property is competitive with the monolayer FET’s

July– Aug, 2013
Summer Research Internship
Advisor: Prof. Debdeep Jena and Prof. Huili (Grace) Xing
Topic1:
·
Fabrication of Multi-layer MoS2 Field Effect Transistors
Fabrication and Characterization of Multi-layer MoS2 FET: achieved 104 gate modulation and improved the Schottky
contact to be Ohmic by annealing
Topic2:
Using Ballistic Model Comparing Mono-layer and Multi-layer MoS2 Field Effect Transistors
·
Conducted simulation of MoS2 FET using Natori’s ballistic model
·
Demonstrated that mono-layer MoS2 FET has lager current density than the multi-layer ones, which indicates that the
effective mass is the major effective factor contributed to the current under room temperature
Washington University in St. Louis

Advisor: Prof. Yu Qi
Topic:
·
The Damage of the Cells of Goldfish After Ultralow Temperature Frozen
Conducted anatomy for the goldfish, made paraffin sections of the Brain samples, Myocardial and Skeletal muscle
samples, dyed with Hematoxylin and Eosin to distinguish the Nucleus and Cytoplasm
·
Observed the broken areas of the tissue samples, which appeared as white spacing between the purple blue nucleus and
pink cytoplasm
·
Demonstrated that broken tissue damage was due to the freezing and unfreezing process of H20 and tissue fluid in cells
