Spin splitting of upper electron subbands in a SiO<sub>2</sub>/Si(100)/SiO<sub>2</sub> quantum well with in-plane magnetic field
We observe a lifting of the twofold spin degeneracy of conduction-band electrons in an upper-valley subband with in-plane magnetic field in a SiO2/Si(100)/SiO2 quantum well, which is manifest in a splitting of a feature in the...

Electrons and holes in a 40 nm thick silicon slab at cryogenic temperatures
We demonstrate low temperature operation of an electron-hole bilayer device based on a 40 nm thick layer of silicon in which electrons and holes can be simultaneously induced and contacted independently. The device allows the...

Electron and hole mobilities at a Si/SiO<sub>2</sub> interface with giant valley splitting
We examine the electron mobility and hole mobility at the Si/buried oxide (BOX) interface at which the valley splitting of the electron system is strongly enhanced, and compare the values observed to those at a standard...
Impact of valley polarization on the resistivity in two dimensions
We examine the temperature dependence of resistivity in a two-dimensional electron system formed in a silicon-on-insulator quantum well. The device allows us to tune the valley splitting continuously in addition to the electron...

Spin and valley polarization dependence of resistivity in two dimensions
We demonstrate that spin polarization and valley polarization have quantitatively similar effects on the resistivity of a two-dimensional electron gas in a silicon-on-insulator quantum well. In so doing, we also examine the...

Separately contacted monocrystalline silicon double-layer structure with an amorphous silicon dioxide barrier made by wafer bonding
A double layer of monocrystalline silicon separated by a 23.5 nm silicon dioxide barrier is fabricated by bonding two silicon-on-insulator wafers with oxidized surface layers. The two layers are separately contacted allowing...
Achieving robustness to aleatoric uncertainty with heteroscedastic Bayesian optimisation
Ryan-Rhys Griffiths, Alexander A Aldrick, Miguel Garcia-Ortegon, Vidhi Lalchand, Alpha A Lee

Metallic behaviour in SOI quantum wells with strong intervalley scattering
V T Renard, I Duchemin, Yoshitaka Niida, Akira Fujiwara, Yoshiro Hirayama, Kei Takashina
Jun 18, 2013
The fundamental properties of valleys are recently attracting growing attention due to electrons in new and topical materials possessing this degree-of-freedom and recent proposals for valleytronics devices. In silicon MOSFETs...
Depression amongst interns working in a tertiary care teaching Hospital in Maharashtra
Background: Internship is a crucial stage of medical school regarding student stress which can affect the patient care negatively. Retrieving knowledge about presence of depression is therefore important in itself and if found...

Right sided eventration of diaphragm with clinodactyly
A. Sareen and K. Mahajan
Apr 21, 2015
Diaphragmatic hernia can be of two types-absence or deficiency of the diaphragm, or eventration resulting in elevation of a portion of the diaphragm as a result of incomplete muscularization. Complete eventration almost...
