Inverse Opal Photonic Gel Containing Charge Stabilized Boronate Anions for Glucose Sensing at Physiological pHPhysica Status Solidi - Rapid Research Letters - Tập 13 Số 2 - 2019
Dongyoun Kim, Young Gook Koh, Wonmok Lee
A glucose‐sensing inverse opal photonic gel (IOPG) that functions at
physiological pH has been demonstrated in this study. Photopolymerization of the
monomer mixtures is templated by opal films. The structural colors of the
optimized IOPG change from red to green upon the addition of the glucose
solution at pH 7.4 due to the formation of 2:1 boronates–glucose complexes which
induces a shrinkage of... hiện toàn bộ
Comparison of InGaN/GaN light emitting diodes grown on m ‐plane and a ‐plane bulk GaN substratesPhysica Status Solidi - Rapid Research Letters - Tập 2 Số 2 - Trang 89-91 - 2008

AbstractInGaN/GaN‐based light emitting diodes (LEDs) grown on m ‐plane, a ‐plane
and off‐axis between m ‐ and a ‐plane GaN bulk substrates were investigated. A
smooth surface was obtained when a ‐plane substrate was applied; however, large
amounts of defects were observed. Photoluminescence measurements of the LEDs
with a well thickness of 2.5 nm revealed that all the LEDs showed the peak
emission... hiện toàn bộ

Diamond is desired for active semiconducting device because of it high carrier
mobility, high voltage breakdown resistance, and high thermal diffusivity.
Exploiting diamond as a semiconductor is hampered by the lack of shallow dopants
to create sufficient electronic carriers at room temperature. In this work,
nanometer thick, heavily boron doped epitaxial diamond ‘delta doped’ layers have
been gro... hiện toàn bộ
Extremely low surface recombination in 1 Ω cm n‐type monocrystalline siliconPhysica Status Solidi - Rapid Research Letters - Tập 11 Số 1 - 2017
Ruy S. Bonilla, Christian Reichel, Martin Hermle, Peter R. Wilshaw
A key requirement in the recent development of highly efficient silicon solar
cells is the outstanding passivation of their surfaces. In this work, plasma
enhanced chemical vapour deposition of a triple layer dielectric consisting of
amorphous silicon, silicon oxide and silicon nitride, charged extrinsically
using corona, has been used to demonstrate extremely low surface recombination.

Unexpectedly High Minority‐Carrier Lifetimes Exceeding 20 ms Measured on 1.4‐Ω cm n‐Type Silicon WafersPhysica Status Solidi - Rapid Research Letters - Tập 11 Số 11 - 2017
Boris Veith‐Wolf, Jan Schmidt
We measure very high minority‐carrier lifetimes exceeding 20 ms on 1.4‐Ω cm
n‐type Czochralski silicon wafers passivated using plasma‐assisted
atomic‐layer‐deposited Al2O3 on both wafer surfaces. The measured maximum
effective lifetimes are surprisingly high as they significantly exceed the
intrinsic lifetime limit previously reported in the literature. We are able to
measure such high lifetimes b... hiện toàn bộ
Silicon surface passivation by ultrathin Al2O3 films synthesized by thermal and plasma atomic layer depositionPhysica Status Solidi - Rapid Research Letters - Tập 4 Số 1-2 - Trang 10-12 - 2010
G. Dingemans, R. Seguin, P. Engelhart, M. C. M. van de Sanden, W. M. M. Kessels
AbstractIn this Letter, we report that both thermal atomic layer deposition
(ALD) with H2O, and plasma ALD with an O2 plasma, can be used to deposit Al2O3
for a high level of surface passivation of crystalline silicon (c‐Si). For 3.5 Ω
cm n‐type c‐Si, plasma ALD Al2O3 resulted in ultralow surface recombination
velocities of Seff < 0.8 cm/s. Thermal ALD Al2O3 also showed an excellent
passivation le... hiện toàn bộ
Thermal activation and deactivation of grown‐in defects limiting the lifetime of float‐zone siliconPhysica Status Solidi - Rapid Research Letters - Tập 10 Số 6 - Trang 443-447 - 2016

By studying the minority carrier lifetime in recently manufactured commercially
available n‐ and p‐type float‐zone (FZ) silicon from five leading suppliers, we
observe a very large reduction in the bulk lifetime when FZ silicon is
heat‐treated in the range 450–700 °C. Photoluminescence imaging of these samples
at the wafer scale revealed concentric circular patterns, with higher
recombination occu... hiện toàn bộ
Photovoltaic effect of BiFeO3/poly(3‐hexylthiophene) heterojunctionPhysica Status Solidi - Rapid Research Letters - Tập 5 Số 10-11 - Trang 367-369 - 2011

AbstractThe photovoltaic effect of the heterojunction based on multiferroic
material BiFeO3 and organic semiconductor poly(3‐hexylthiophene) has been
studied for the first time. A typical rectifying J–V characteristic of the
heterojunction is observed with a rectifying ratio of ∼103. The power conversion
efficiency of the device is comparable to those of hybrid solar cells based on
poly(3‐hexylthi... hiện toàn bộ
