Doping against the native propensity of MoS2: degenerate hole doping by cation substitution.
Joonki Suh,Tae Eon Park,Der Yuh Lin,Deyi Fu,Joonsuk Park,Hee Joon Jung,Yabin Chen,Changhyun Ko,Chaun Jang,Yinghui Sun,Robert Sinclair,Joonyeon Chang,Sefaattin Tongay,Junqiao Wu,Junqiao Wu +14 more
TL;DR: Stable p-type conduction in MoS2 is demonstrated by substitutional niobium (Nb) doping, leading to a degenerate hole density of ∼ 3 × 10(19) cm(-3), and it is expected that the synthesis technique demonstrated here can be generally extended to other TMDs for doping against their native unipolar propensity.
Journal ArticleDOI
Efficient, stable silicon tandem cells enabled by anion-engineered wide-bandgap perovskites
Daehan Kim,Hee Joon Jung,Ik Jae Park,Bryon W. Larson,Sean P. Dunfield,Sean P. Dunfield,Chuanxiao Xiao,Jekyung Kim,Jinhui Tong,Passarut Boonmongkolras,Su Geun Ji,Fei Zhang,Seong Ryul Pae,Minkyu Kim,Seok Beom Kang,Vinayak P. Dravid,Joseph J. Berry,Joseph J. Berry,Jin Young Kim,Kai Zhu,Dong Hoe Kim,Dong Hoe Kim,Byungha Shin +22 more
TL;DR: It is shown that by using phenethylammonium as a two-dimensional additive, along with iodine and thiocyanate, bromine-rich perovskite films can be stabilized and, by doing so, improve the carrier mobility and stability in silicon tandem solar cells.
Journal ArticleDOI
High spectral resolution of gamma-rays at room temperature by perovskite CsPbBr3 single crystals
Yihui He,Liviu Matei,Hee Joon Jung,Kyle M. McCall,Michelle Chen,Constantinos C. Stoumpos,Zhifu Liu,John A. Peters,John A. Peters,Duck Young Chung,Bruce W. Wessels,Michael R. Wasielewski,Vinayak P. Dravid,Arnold Burger,Mercouri G. Kanatzidis +14 more
TL;DR: An improved melt growth method for cesium lead bromide and a special detector design with asymmetrical metal electrode configuration that leads to a high performance at room temperature are reported.
Journal ArticleDOI
Oxygen Surface Exchange at Grain Boundaries of Oxide Ion Conductors
Won Young Lee,Hee Joon Jung,Min Hwan Lee,Young Beom Kim,Joong Sun Park,Robert Sinclair,Fritz B. Prinz +6 more
TL;DR: In this article, the role of grain boundaries on oxygen surface exchange in an oxide ion conductor is reported, showing that higher grain boundary density results in lower electrode impedance and higher exchange current density.
Journal ArticleDOI
Laser-synthesized epitaxial graphene.
Sangwon Lee,Michael F. Toney,Wonhee Ko,Wonhee Ko,Jason C. Randel,Jason C. Randel,Hee Joon Jung,Ko Munakata,Jesse Lu,Theodore H. Geballe,M. R. Beasley,Robert Sinclair,Hari C. Manoharan,Alberto Salleo +13 more
TL;DR: Laser-synthesized graphene does not display some of the structural characteristics observed in EG grown by conventional thermal decomposition on SiC (0001), such as Bernal stacking and surface reconstruction of the underlying SiC surface.
